[pgpool-committers: 3752] pgpool: Fix for 0000249: watchdog sometimes fails de-escalation.

[Muhammad Usama]

Fix for 0000249: watchdog sometimes fails de-escalation.

The logic in pgpool-II main process exit_handler and terminate_all_childrens was
not making sure that pgpool-II main process should only exit after all its
children have exited. And the problem occurs when the main process shutdowns
itself before watchdog and de-escalation child processes.

The solution is to use the waitpid() system call without WNOHANG option.
