Conclusion: vfork is totally weird :-)

Now you've got me curious about something different.  Is vfork really 
that much faster on
modern systems with MMUs?  Certainly I could see it being faster on a system
without an MMU, where presumably there's no such thing as copy-on-write, 
but with
an MMU does it really take a noticable amount of time just to copy the 
page tables for
reasonable-sized processes?

Will do.
