        !            13: assigns 
        !            14: .I sigmask
        !            15: to the set of masked signals
        !            16: and then waits for a signal to arrive;
        !            17: on return the set of masked signals is restored.
        !            18: .I Sigmask
        !            19: is usually 0 to indicate that no

        !            21: .I Sigpause
        !            22: always terminates by being interrupted, returning EINTR.

        !            24: In normal usage, a signal is blocked using

        !            26: to begin a critical section, variables modified on the occurance
        !            27: of the signal are examined to determine that there is no work
        !            28: to be done, and the process pauses awaiting work by using
