If you mean pthread_kill() with "posting to a thread", then that does
not seem a bug. I expect that pthread_kill() signals are lost when a
thread exits and that pthread_kill() to a thread that has already
terminated but has not yet been joined does nothing (possibly returning
an error).

If a SIGKILL from kill() is lost, that is a bug.
