pthread_testcancel(3) contains a list of functions that should have a
- clock_nanosleep() mentioned in pthread_testcancel(3) should probably be
- sem_timedwait() mentioned in pthread_testcancel(3) should probably be
- waitid() mentioned in pthread_testcancel(3) should be ????
- pkg/45131 contains a fix for csup that's wrong. It looks like sigwait()
(implemented in libc as a wrapper around sigtimedwait()) isn't calling the
sigtimedwait() wrapper in pthread_cancelstub.c when using sigwait() in a thread
(like csup does)
pthread_testcancel(3) should contain the changes mentioned earlier.
sigwait() cancellation point could be fixed with another entry in
pthread_cancelstub.c but that doesn't look right to me.
