Subject: [PATCH 8/9] Fix invalid sigprocmask call
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The POSIX document says

    The pthread_sigmask() and sigprocmask() functions shall fail if:

    [EINVAL]
    The value of the how argument is not equal to one of the defined values.

and this is how musl-libc is currently doing.  Fix the call to be safe
and correct
