Our system (initially prototyped in CLIPS, using modules) exhibits
these same characteristics. We addressed the problem in JESS using two
techniques; 1) separate Rete instances for the "large" partitioning
work, where the rulesets in each instance are logically separate; and
2) control facts to drive the systems running within each Rete
instance. The system is fairly elegant (credit to Jess here), but
modules would have obviated the need (at least in our system) for most
control facts.
