I'm profusely embarassed about this.  I posted a very close follow-up message
correcting the mistake (which I caught fairly quickly) in no uncertain terms.
 
The new FreeBSD does a proper vfork(), just as the new NetBSD does; in fact, the
code is very similar.  So the issue of how FreeBSD would handle COW doesn't
even arise in this case.

The first time I looked at the FreeBSD source, I got confused by the alien flag
definitions and new functions and took the wrong turn.  The second time it was
very clear.

Sorry about that!
