Why do you need a different timeout API?  It either works or it
doesn't.  Provide an implementation of send*/receive*/sockopt APIs
that can use SO_SNDTIMEO/O_RCVTIMEO, and enable it carefully.

As far as I recall, it was just the lack of portability even among
Unix-ish platforms.  ifdef SO_SNDTIMEO probably isn't a good-enough
check for availability.
