I am working on a medium-sized enhancement to the design of ObjectHandler.
 At present, there are certain series of events which can lead to objects
being orphaned in memory - not quite leaked, but effectively the same
thing.  The enhancement would prevent this error and I hope to include it
in the next release.

Part of the enhancement would be to rework some of the garbage collection
code which contains the bug that you found above.  So I will ensure that
the bug is fixed as part of that project.  Many thanks for your detailed
description of the problem.

Regards,
Eric
