- At the top of sleepq_catch_signals() lock the thread and check TDF_NEEDSIGCHK
before doing the very expensive cursig() and related locking. NEEDSIGCHK
is updated whenever our signal mask change or when a signal is delivered and
should be sufficient to avoid the more expensive tests. This eliminates
another source of PROC_LOCK contention in multithreaded programs.
