10 * to allow signals to be sent reliably.

88 * Tracers may want to know about even ignored signals.
95 * signals, globally pending signals, and blocked signals.
176 * synchronous signals that need to be dequeued first.
288 * Flush all pending signals for a task.

380 * process, and wants to be notified if any signals at all were to be

577 * Remove signals in mask from the pending set and queue.
578 * Returns 1 if any signals were found.
582 * This version takes a sigset mask and looks at all signals,
604 * Remove signals in mask from the pending set and queue.
605 * Returns 1 if any signals were found.
685 * Handle magic process-wide effects of stop/continue signals. Unlike
689 * signals. The process stop is done as a signal action for SIG_DFL.
715 * Remove all stop signals from all queues,
785 * have pending signals. Such threads will dequeue from the shared queue
818 * It will dequeue unblocked signals before it runs again.
