Moderate (not easy, since it wouldn't work on all platforms).  Perhaps an
elaboration of NSL_FORK would be a starting place.

if it's waiting for a response - again, not easily ported (the way to do
this on a Unix system is using an alarm, which may interrupt the system
call in progress, causing it to fail - working around that tends to get
complicated: yes, I'm well aware of the handful of 'modern' systems where
this is not a problem).
