I figured this out a little later.  I'd been discussing UVM, and I have such a
one-track mind....

I'm getting ready to "back-port" your new vfork() into NetBSD 1.2/i386, so I can
test the difference objectively.

This doesn't look like it ought to present any difficulties -- except that in
the i386 port cpu_wait() is a null #define, so the two "user structure"
allocations apparently never get freed on exit.  (Unless I missed the place
where they get freed, which wouldn't be too surprising...)
