The sleep_on* series of calls is unsafe, and prone to race conditions.
They've been unofficially deprecated for a while.  Instead, we're
supposed to use the wait_event* series of calls.

There's only one problem with this.  There's no equivalent of
sleep_on_timeout/interruptible_sleep_on_timeout.

So, the attached patch adds 'wait_event_timeout' and
'wait_event_interruptible_timeout'  The diff is generated against
2.4.20-pre7, but should apply cleanly to just about any 2.4/2.2 release,
and maybe even 2.5 as well.

Back to the bit mines..
