I think the thrust of my question was not quite clear and perhaps my
skimming over swarmapps examples (inforamtion overload, again) missed
something.

My problem is essentially: how do I (as programmer, not user) get control of
the swarm application once variables have been changed or methods invoked?
(c.f. the use of user-defined interrupt handlers in C after a given
interrupt).  For instance, if I decrease the number of swarm objects
(agents), I would want to kill off some of them and restore any other agents
that depend on them in a sensible state before resuming execution.

I'm not sure I am swarm-mature enough to tackle the task.  But I did
download the packages RepeatingHeatbugs and Majority_rule 1.1, but they only
crash my system!  (I am still on Swarm 1.3.1 (windows 95), with no
temptation to move to 1.4.1 before 2.0 !)
