   Status:      Open.  There is some temporary logic to examples/nsh that does
                this same fix and that temporary logic should be removed when
                send() is fixed.
   Priority:    Medium-Low.  This is an important issue for applications that
                send on the same TCP socket from multiple threads.

   Description: TCP supports read-ahead buffering to handle the receipt of
                TCP/IP packets when there is no read() in place.  Should such
                capability be useful for UDP?  PRO: Would reduce packet loss
