periodic event processing

[rhino@media.mit.edu]

I have a function that I would like to call periodically (it checks a
QuickTime movie to see if it has played out to the end).  I put it
into *eventhook*.  This works but it significant slows performance.
How can I specify a longer interval between each call to my handler
(e.g. every 2 seconds).


thanks,

ryan
