CVS commit: src/regress/lib/libpthread/sigmask3

[Andrew Doran <ad%netbsd.org@localhost>]

Module Name:    src
Committed By:   ad

Modified Files:
        src/regress/lib/libpthread/sigmask3: sigmask3.c

Log Message:
Signal masks are thread private, and there is no guarantee of the order in
which the two signal handlers in this test will execute, at least not beyond
SIGUSR1 being caught first, and SIGUSR2 being caught after that. One way
that it can fail erroneously is:

    2    kill(getpid(), SIGUSR1)
    2    Receive signal SIGUSR1
    2    kill(getpid(), SIGUSR2)
    1    Receive signal SIGUSR2
    1    Exit handler
    2    Exit handler

So if the handlers appear not to have run in sequence, at least verify
that they were run by different threads.
