Re: [PATCH 2/2] nptl: Add pthread_clockjoin_np

I would prefer -1, just because, on Linux, 0 is CLOCK_REALTIME.

I would prefer do_test_clock() having another parameter to enable usage
of pthread_clockjoin_np() than having a "fake" clock identifier used as
a boolean.

What's the behavior when __abstime is NULL ?
pthread_timedjoin_np()'s code seems to behave like pthread_join() if
__abstime is NULL. This behavior is fine but not documented.
