Memory leak in swarm 2.0.1?

[jalex]

This afternoon I noticed a slight memory leak in one of my programs,
built around the ExperimentSwarm design from the tutorials.  I list
below the lines grabbed from "top" which (I think) indicate this.  You
can see that the number of kilobytes used steadily increases by four
approximately every minute.  (This happens even when I compile the
model under the newest 2.0.1 RPMS available from SFI.)

There's a chance I might be doing something wrong in my implementation
of [ModelSwarm drop].  Just for the record, here it is:


// ModelSwarm drop
- (void) drop
{
  [game drop];
  [agentSet removeAll];
  [agentSet drop];
  [world drop];
  [populationStatistics drop];
  [super drop];
}


// Definition of ModelSwarm
@interface ModelSwarm: Swarm
{
  int generation;

  id <Grid2d> world;
  id game;
  ParameterManager *parameterManager;
  PopulationStatistics *populationStatistics;

  id agentSet;

  id modelActions; 
  id modelSchedule;
  id stopSchedule;
}


Any suggestions would be much appreciated, as this leak prevents me
from setting up a series of experiments to crank out over a couple
days.


Thanks,

Jason
