This is indeed an interesting venture. Look what I found:

(http://lists.apple.com/archives/macnetworkprog/2002/Dec/msg00091.html)

--- start ---
Mac OS X does not support the flag MSG_NOSIGNAL but we have an equivalent.

Starting with version 10.2 (Jaguar), Mac OS X has the socket option
SO_NOSIGPIPE that prevents SIGPIPE from being raised when a write fails on a
socket to which there is no reader; instead the write to the socket returns
with the error EPIPE.
--- stop ---

Thus, we should check for SO_NOSIGPIPE and use that. If I make a fix for this,
can you try it out?
