Are you sending a lot of data? That should only happen if you send more than 
a buffer, whatever that is, only the system knows. It blocks for exactly one 
second if the buffer is full, I was thinking that should give it enough time 
to send everything. I guess Pd isn't crashing anymore at least ;)
You could try changing line 383 of tcpserver.c to change the timeout:
timeout.tv_sec = 10; /* for ten seconds */
