Re: Memory exhaustion

Here is how the code could be changed to use FAction instead of
ActionTo.  Another change to make is to use java.util.{List,LinkedList}
instead of swarm.collections.{List,ListImpl}.  That will have the
advantage of using not using Objective C objects to track agents, and
thus requiring no proxy objects.  It will have a smaller footprint and
be faster.
