I posted a patch a while back that caused the read function to behave semi 
nonblocking and return EAGAIN if no data was available. You could potentially 
use that. 
http://thread.gmane.org/gmane.comp.video.ffmpeg.devel/57508/focus=57881

But as Luca pointed out. It's not entire complete as it could still stall 
during a read + it's not really the correct use for that flag as sockets are 
really not nonblocking.

A complete implementation of nonblocking reads or fixing up the abort function 
to give context would be accepted as a patch.
