(pending_signals::pending): Force an additional loop through wait_sig by setting retry whenever this function is called. (sig_send): Reorganize to wait for SIGHOLD at bottom. Always add signal to pending queue and work on whole queue rather than just the one signal. Loop when sigq.retry is set. Fix long-broken check for SIGCHLD after queued signals.
