[PATCH] Fix tst-cond22.c

[Jakub Jelinek <jakub at redhat dot com>]

Hi!

tst-cond22.c occassionally fails with
first thread not canceled
cond = { 0, 2, 1, 1, 1, 0x804b140, 0, 0 }
cond = { 0, 4, 2, 2, 2, 0x804b140, 0, 0 }

The problem is that it relies on tf thread not being woken up (with
pthread_signal) before pthread_cancel is run.  If tf is woken before
pthread_cancel is called in the initial thread, then the thread just runs
through until return NULL; and exits.
Alternatively, we could if (res == NULL) just try again a few times and only
give up (with no error) if the "first thread" has not been successfully
cancelled for say 16 or 32 times.

	* tst-cond22.c (do_test): Don't insist the first thread has to be
	cancelled.
