I'm guessing the issue is nash just calls wait and doesn't check the

Which is valid except when you are running as pid == 1.

Hm, that's always a bug; a process can always have children it doesn't
expect (think forking, and then the parent execs).

Not if the process already forked.

But yes, in general this is a major screwup.
