Allow waitpid(-1, Process::WNOHANG) to be woken if a waitpid(pid) is
...pending
If two threads are running, with one calling waitpid(-1, Process::WNOHANG),
and another calling waitpid($some_pid), and then
$some_other_pid exits, we would expect the waitpid(-1,
Process::WNOHANG) call to retrieve that exit status. However, it
cannot actually do so until $some_pid _also_ exits.
This patch fixes the issue by calling do_waitpid unconditionally in
waitpid_wait; this will ensure that a waitpid -1 actually reaps
something (after first checking that no PID-directed call wants the
process).
