There's already SO_RCVTIMEO for setsockopt() which should be usable for the
purpose on the client side...?
The thing is, RFC-793 is pretty clear about when to RST and when not to.
You're supposed to RST connection attempt requests when you know they are
invalid (ie, to a port which is closed and so forth); but there is nothing
which suggests it's OK to RST for a valid connection attempt to an open port--
see the "SEGMENT ARRIVES" section.
