Matt, 
 as per my previous response.. 
http://sources.redhat.com/ml/cygwin/2000-08/msg00315.html

there is a workaround...

I haven't had time to look at checking the flags in the fcntl call and
calling ioctl for non-blocking and related things (I'm not even sure
that would be the best way to hadnle this - Comments anyone?) so I
believe you have two choices to solve your problem .. work around it or
submit a patch for cygwin1.dll
