Okidoki, let's do this then. I'll move this thread to Zope-dev too.

First some jerking to get things straight:

I still think we should do the scheduler with a queue, we can always 
convert to multiple threads later. Let's keep it simple and expand.

Scheduled Event objects are to be based on DTML Methods with some extra 
properties to set up frequence, etc.

The Scheduler is a Folder object that only allows Event objects to be 
added. At least, I haven't thought of any scenario where it would be useful 
to add anything else.

I am still thinking of a queue implementation, where worker threads pick 
off events to execute. Events are inserted into the queue based on who's 
next to be executed.

An event has only one reference in the queue, and is put back on after 
execution (so long running methods that are scheduled to run every second 
won't get executed that often).
