Do not handle SIGPIPE on multithreaded apps, and ask the caller to do 
that? The current code doesn't block SIGPIPE reliably, which makes it 
totally useless (except that it's a debugging nightmare, because 
triggering it depends on the right timing).

Linux has as MSG_NOSIGNAL flag for send(), but that seems to be Linux 
specific.
