sleep()

[ka at spanky.UUCP]

The problem with implementing sleep by setting a flag when the alarm
signal is received and testing for this flag in a loop around the call
to pause() is that the alarm signal may come in between the time the
flag is checked and pause is called.  This may be an improbable occurance,
but I have seen it happen with a version of sleep that works exactly as
Chris proposes.
