** Timers created with run-at-time now work internally to Emacs, and<BR>
no longer use a separate process.  Therefore, they now work more
reliably and can be used for shorter time delays.
<P>
The new function run-with-timer is a convenient way to set up a timer
to run a specified amount of time after the present.  A call looks
like this:
<P>
  (run-with-timer SECS REPEAT FUNCTION ARGS...)
<P>
SECS says how many seconds should elapse before the timer happens.
It may be an integer or a floating point number.  When the timer
becomes ripe, the action is to call FUNCTION with arguments ARGS.
<P>
REPEAT gives the interval for repeating the timer (measured in
seconds).  It may be an integer or a floating point number.  nil or 0
means don't repeat at all--call FUNCTION just once.
