How does this interact with SIGCHLD and the wait system call (or any
wait function without an explicitly specified PID)?

I understand that I have somewhat conflicting requirements, but in terms
of relative priorities, launching a process without spurious signals and
wait notifications would probably offer the larger benefit.
