Well on Unix I don't think you can do that, can you?  You can't 
tell the system that you're not going to be calling "wait4" on a
particular PID... or can you?  If not, the portable thing to do
is to do what I said... register a GC cleanup such that when
a Process.T goes out of scope the runtime does a Process.Wait in
the background.  It'd work on both Unix and Windows and use existing
code rather than introducing a new abstraction.  One issue is that
with my SIGCHLD modification you will get zombies if you don't call
wait4 on Unix.  Process.i3 does mention this possibility so I don't
think I "broke" anything.  (Coding to the specification cuts both
ways...)
