Maybe this can be an idea:
http://xyne.archlinux.ca/manpages/cronwhip
Citing from that page:

I think that solves the wrong part of the problem.
at, which is already in base, also runs overdue jobs upon startup.
Running jobs at boot time (or half an hour later) has been proposed
before, and the problem with that is: it might overload the system
exactly when you want to use it for some real work.
That's well recognized. Some have first hand experience of the problem,
too.
The maintenance(8) proposal solves this by only running the cheap
parts half an hour after boot, such that maintenance doesn't
seriously slow down your work. In that scenario, skipping the cheap
part in case it ran the day before is hardly worth the effort.
Running at any fixed interval after boot, 30 min above there, risks
shifting the problem a bit later. Even with the random interval from an
earlier message, there is the risk of the administrative load coming at
a bad time or too much at the same time.

Well, it seems clear that everyone agrees on two things
1. These scripts need to be run.
2. Pretty much anytime they are run, the will cause problems for the users.
Therefore , we need a new solution to correct problem #2
I propose a new function be added:
$ sleepuser
This new command will temporarily sleep all users until scripts
complete. This will prevent any "apparent" loss of productivity for the
users
