it occurs to me.... if this is occurring asynchronously, not much you 
can do aside from your fix.  but if it's happening on a send() or recv() 
on the socket, passing MSG_NOSIGNAL in the 'flags' parameter will also 
cause this behaviour to stop.  that may just be for send(), i think, 
actually.  of course, just ignoring sigpipe entirely is much easier ^_~.

(you might also be able to use ioctl() or fcntl() on the socket 
descriptor to disable this; i don't recall offhand.)
