Thanks, with send() it works fine.
I think it should be documented in setsockopt(2).
Try this patch. The comment doesn't reflect what the code does. SIGPIPE
may actually be getting queued twice in your case. It is most likely
that the process's main thread wasn't preempted before return from the
syscall.
Perhaps someone more familiar with the signal code than I can chime in.
