Yes, but I don't use (test) it!
It's a small patch but a major change to faxq behavior :
- now runScheduler is not the main function 
- out of date jobs will not be process in the same order
- idem for events
- runScheduler could exit with dead jobs in the run queue
- run queue could become very large,(spool directories).
and so on.

So old problems could pop up, and many new ones could pour in :(

It's up to you.
