I agree. The focus of quartz seems very different than that provided by 
event and that needed by the use cases Vadim listed. Looking at the 
JobScheduler interface I can't shake off the feeling that cron is not 
the canon (honestly it's quite a beast!) best fitted to shoot the flies 
we are dealing with.

I'd much prefer we implement our own excalibur event (why not just fork 
it? it's good code!)
