That is making the oft-repeated assumption that there actually *is*
something that could be done to fork.

At this point, I'd even take ideas over patches.  However I'd like
informed ideas not "Say, I've heard that you can do copy-on-write
on Windows -- just make fork use that."

FWIW, /bin/sh uses vfork these days which, is basically just a spawn
call with some fd table copying overhead.
