--- Comment #5 from [email protected] --- A commit references this bug: Author: kib Date: Fri May 12 15:35:00 UTC 2017 New revision: 318243 URL: https://svnweb.freebsd.org/changeset/base/318243 Log: Do not wake up sleeping thread in reschedule_signals() if the signal is blocked. The spurious wakeup might result in spurious EINTR. The reschedule_signals() function is called when the calling thread has the signal mask changed. For each newly blocked signal, we try to find a thread which might have the signal not blocked. If no such thread exists, sigtd() returns random thread, which must not be waken up. I decided that re-checking, as suggested by PR submitter, is more reasonable change than to change sigtd() interface, due to other uses of sigtd(). signotify() already performs this check.
