  Title:       THE ARP ISSUES AGAIN
  Description: The first GET received by THTTPD is not responded to.  Refreshing the page
               from the browser solves the problem and THTTPD works fine after thatg.  I 
               believe that this is the duplicate of another bug: "Outgoing [uIP] packets are dropped
               and overwritten by ARP packets if the destination IP has not been mapped to a MAC."

  Title:       THTTPD WARNINGS
  Description: If the network is enabled, but THTTPD is not configured, it spews out lots
               of pointless warnings.  This is kind of annoying and unprofessional; needs to
               be fixed someday.
  Status:      Open.  An annoyance, but not a real problem.

  Title:       WGET UNTESTED
  Description: The wget command has been incorporated into NSH, however
               it is still untested as of this writing (only because I
               have not had the correct network setup for the testing
               yet).  Since wget depends on the also untest uIP resolv/
               logic, it is like non-functional.

  Title:       IFCONFIG AND MULTIPLE NETWORK INTERFACES
  Descripton:  The ifconfig command will not behave correctly if an interface
               is provided and there are multiple interfaces.  It should only
               show status for the single interface on the command line; it will
               still show status for all interfaces.
  Status:      Open
  Priority:    Low (multiple network interfaces not fully supported yet anyway).

  Title:       RE-DIRECTION OF BUILTIN APPLICATONS
  Description: There is a problem with the re-direction of output form built-in
               applications in NSH.  When output is re-directed, exec_builtin()
               spawns a tiny trampoline task that re-directs the output as
               requested, starts the built-in task and then exit.

               The problem is that when exec_builtin() starts the trampoline task,
               it receives and returns the pid of the trampoline task, and *not*
               the pid of the desired builtin application.  This bad pid is returned
               to NSH and when NSH tries to use that pid in the waitpid() call, it
               fails because the trampoline task no longer exists.

               The same tasking arrangement is used by the standard function
               posix_spawn().  However, posix_spawn uses the non-standard, internal
               NuttX interface task_reparent() to replace the childs parent task
               with the caller of posix_spawn().

               exec_builtin() should not use this internal interface, however,
               since it resides in the application space.  The suggested solution
               is (1) move the exec_builtin() logic into nuttx/sched, (2) make it
               a semi-standard interface renamed to task_spawn() and prototyped
               in nuttx/include/sched.h, and then (2) use task_reparent to solve
               the parental problem in the same way that posix_spawn does.

  Title:       READLINE IMPLEMENTATION
  Description: readline implementation does not use C-buffered I/O, but rather
               talks to serial driver directly via read().  It includes VT-100
               specific editting commands.  A more generic readline() should be
               implemented using termios' tcsetattr() to put the serial driver
               into a "raw" mode.

  Priority:    Low (unless you are using mixed C-buffered I/O with readline and

  Title:       EXAMPLES/PIPE ON CYGWIN
  Description: The redirection test (part of examples/pipe) terminates

  Title:       EXAMPLES/NX FONT CACHING
  Description: The font caching logic in examples/nx is incomplete.  Fonts are
               added to the cache, but never removed.  When the cache is full
               it stops rendering.  This is not a problem for the examples/nx
               code because it uses so few fonts, but if the logic were
               leveraged for more general purposes, it would be a problem.
               Update: see examples/nxtext for some improved font cache handling.
  Status:      Open
  Priority:    Low.  This is not really a problem becauses examples/nx works
               fine with its bogus font caching.

  Title:       EXAMPLES/NXTEXT ARTIFACTS
  Description: examples/nxtext.  Artifacts when the pop-up window is opened.
               There are some artifacts that appear in the upper left hand
               corner.  These seems to be related to window creation.  At
               tiny artifact would not be surprising (the initial window
               should like at (0,0) and be of size (1,1)), but sometimes
               the artifact is larger.
