I have no clue as to what could have happened... other than a lot of Scala
Actors sending messages to each other (each thread created by the FJ library
has its own thread-local pool that expands the many MB, thus why we're
moving Lift off Scala Actors entirely).  So, the act of sending a message
causes memory to be retained.

I'd suggest migrating ESME to Lift's Actors (I can do this today if folks
want) and that should take care of the Actors retaining memory problem.
