Status: Open, depends on UDP read-ahead support
Priority: Medium
+ Description: poll()/select() only works for availability of buffered TCP
+ read data (when read-ahead is enabled). The way writing is
+ handled in uIP, all sockets must wait when send and cannot
+ be notifiied when they can send without waiting.
+ Status: Open, probably will not be fixed.
+ Priority: Medium... this does effect porting of applications that expect

buffering is enabled, and (2) TCP/IP accept() operations when TCP/IP
