the STREAMS related functions. This affects
getmsg() getpmsg() putmsg()
putpmsg()
lockf() and fcntl() are tested in tst-cancel16.
pthread_join() is tested in tst-join5.
pthread_testcancel()'s only purpose is to allow cancellation. This
is tested in several places.
sem_wait() and sem_timedwait() are checked in tst-cancel1[2345] tests.
mq_send(), mq_timedsend(), mq_receive() and mq_timedreceive() are checked
in tst-mqueue8{,x} tests.
aio_suspend() is tested in tst-cancel17.
clock_nanosleep() is tested in tst-cancel18.
