I could give it a try - but I can only test it on GNU/Linux,
so I will need to make some sensible choices about how to
conditionally support this feature.
I think I will need to test for the availability of HAVE_SELECT,
F_SETFL, O_NONBLOCK, and HAVE_GETPEERNAME (which is used to check
whether the connect actually succeeded).
But that might not work on all systems, so I may need to add a
BROKEN_NON_BLOCKING_CONNECT define which can be set for systems where
this doesn't work (just to be defencive).
There is currently no HAVE_GETPEERNAME check in configure, but I
suppose that can be added (by someone who speaks autoconf :-)
