Modified Files:
        src/tests/lib/libpthread: t_sem.c

Log Message:
Split the before_start test in two: one that does not use threads and one
that does.  The former works all the time but the latter gets consistently
stuck on amd64.  Mark the latter as an expected timeout (should be a "race
condition" test, but atf does not have such a thing yet[1]).

This clears the test failures, at least, under anita running NetBSD/i386.

From pooka@: this could well be because calling sem_post(3) from a signal
handler can't possibly do the right thing with the pthread implementation.
However, according to signal(7), sem_post(3) is signal-async safe...

While here, program alarms using a timeout shorter than 1 second to speed
up the execution of the tests.

1: Good thing is I finally understand what a "race condition" test looks
like, I believe.
