There is a directory that associates Java objects with Objective C
objects.  Only Java objects that somehow touch Swarm interfaces (say,
targets of Actions), have entries in this directory.  By virtue of
being in this directory, the Java-side objects aren't touched by
garbage collection.  When you have agents that subclass from Swarm
classes (say SwarmObjectImpl), then it is necessary to drop them
explicitly to remove them from the directory.

So, one piece of advice is to avoid subclassing agents from
SwarmObjectImpl.  Realize that instances of any *Impl class in
swarm.*.* packages are immune from garbage collection.
