There is a difference between using random PIDs (which should not
cause a problem) and re-using PIDs. I've seen some shell scripts
which start a child process and then kill it after some time. When
the child exists and the PID has been re-used in the meantime, this
would subtly break. Agreed this is a somewhat broken as it relies
on some time frame before PIDs are re-used but this is safe with
the current aproach.
