*shrug* works on unix, exactly as-is.  I used it for a few days under  
Mac OS X to test some hardware I was developing.

My guess is the problem is related to long sleep()s or running it  
under windows (which you are doing, IIRC, and I never have).  If you  
are sleep()ing for several minutes and your network connection yo-yos  
in the mean time your socket may die.  If the time between packets is  
more than tens of seconds and the network connection is less than  
100% reliable I'd open a socket, send the packet, and close the  
socket, _then_ sleep().

If there are actual bugs I'd appreciate hearing about them, as I've  
distributed that code a bit and haven't heard of any yet.
