In the bug thread I proposed making atexit_callback check whether getpid()

atexit callback list, along with the value of MyProcPid, from some parent

in that?
There's the PID reuse problem. Forking twice (with a delay) could end
up with the same PID as MyProcPid.
Not if the parent process is still running.
