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.
