There are a bunch of cron scheduler thingies on the CPAN, i think we
should use one of them instead of rolling our own.

Also, how does it get initiated?

I was thinking the simplest way to run it is via a cron script, and
the catalyst scheduler thing just checks if it needed to do
something between the last invocation and this one.

This does not contradict:...

This seems to imply that it runs after finalize if needed... How
does this work with respect to long running jobs?

I think we should support both invocation styles.

I also things that plugins should be able to register for scheduled
events... For example the session store plugins have a default daily
run of delete_expired_sessions, but the user can change (or disable)
this.
