I checked in some (slightly less broken) PID and parentage restore code.
I just tested exec() with pthreads after a restart, and it looks like
it works correctly. So the LAM folks ought to be in a better spot.
There are a number of caveats, this code hasn't been well tested, but works
ok most of the time.
One major caveat: cr_restart WILL NOT WORK if you have any other tasks
in the background. If you do something like:
xterm &
cr_restart foo
It will fail.
(I'll fix this quicker if this is a showstopper for anyone, but for now,
just make sure that cr_restart has no sibling processes when you run it.)
