Hey Steve,
You should probably dynamically add the migrantActions after
so many steps have gone by, using:

  [modelActions createAction: migrantActions];
  [modelSchedule remove: triggerAction];

You would add the migrantActions group to the main actionGroup
in some routine that was triggered at the appropriate time.
Then you'd have to forcibly drop that trigger action so that
it didn't get repeated.  Adding the action might look like:

 triggerAction = [modelSchedule at: 100 
         createActionTo: self message: M(triggerMigrants)];


I think something like this would work.
