Help Measuring Fork/Exec Overhead

Copy-on-write...  I've done it.  It IS a speedup because of the
exec() usually following the fork().  But, I've done it on 32V
which is a VAX swapping system (ie. not bezerkely paging).

We don't swap so much now and our fork()'s are at least twice as fast.
It's about 200 lines of code.  I'm thinking about doing it here
with V8.  That'll be a different story though.
