        !            11: The current process is suspended from execution for the number
        !            12: of seconds specified by the argument.
        !            13: The actual suspension time may be up to
        !            14: one
        !            15: second less than
        !            16: that requested, because scheduled wakeups occur at fixed

        !            22: The routine is implemented by setting an alarm clock signal
        !            23: and pausing until it occurs.
        !            24: The previous state of this signal is saved and restored.
        !            25: If the sleep time exceeds the time to the alarm signal,
        !            26: the process sleeps only until the signal would have occurred, and the
        !            27: signal is sent one second later.
