        !             5: .SH SYNOPSIS

        !             7: .B sleep(seconds)

        !            10: .SH DESCRIPTION
        !            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 1 second less than
        !            14: that requested, because scheduled wakeups occur at fixed 1-second intervals,
        !            15: and an arbitrary amount longer because of other activity
        !            16: in the system.
        !            17: .PP
        !            18: The routine is implemented by setting an interval timer
        !            19: and pausing until it occurs.
        !            20: The previous state of this timer is saved and restored.
        !            21: If the sleep time exceeds the time to the expiration of the
        !            22: previous timer,
        !            23: the process sleeps only until the signal would have occurred, and the
        !            24: signal is sent 1 second later.
        !            25: .SH "SEE ALSO"
        !            26: setitimer(2), sigpause(2)
        !            27: .SH BUGS
        !            28: An interface with finer resolution is needed.
