I've used NSFileHandle for socket I/O on solaris 8 and 9 quite a  
bit ... and not noticed any problems.
I think it would be good to use NSLog() to write stuff to stderr to  
tell you exactly what it does  in GSFileHandle.m, and when it does  
it ... for instance, it would be good to confirm the exact timing of  
the sequence ...

client initiates connect
server accepts incoming connection
client gets notification that connection has been made, and starts  
write,
server reads data
client write completes
notification of read completion in server is handled.
