Hi all,

I've been working on (or rather, struggling with) with the scsh-process egg
for a bit the past couple of days, and I've been thinking about fork.
It's probably better if we clean up the parent process state that's lying
around in the child's continuation of a (process-fork) call which we will
never call anyway.

This should avoid issues like we've seen with #1367 when forking lots of
processes, and in general decrease memory use of child processes.

Initially I thought I could just (##sys#call-with-cthulhu thunk) because
the C_termination_continuation also exits with code 0, but then
I remembered that (exit) will call ##sys#exit-handler (which the C code
will not do), so I think this patch is correct.

Both for master and chicken-5.
