Use the current 'cron' and put idprio in form of the 'slow' jobs in the crontabs. Problem with this is that is inelegant, mixes up different job classes, rwuire maintenance and is only useful to root. 2. What I would suggest was running a sceonf copy of cron in a chrooted jail at idprio. All jobs kicked of by this second chrooted, idprio'ed cron should run at idle priorities. 3. Take a look at the various queue managing facilities provided by 'at. You can pick queues, set ques with different priorities, maximum concurrent jobs etc. This may very will be exactly what you want.
