Using Vince Bonfanti's excellent GaeVFS pkg I am getting this
exception trace from the Task Queue API...
com.google.appengine.repackaged.com.google.common.base.FinalizableReferenceQueue
<init>: Failed to start reference finalizer thread. Reference cleanup
will only occur when new references are created.

This looks like a problem in the AppEngine TaskQueue code ...
any thoughts/suggestions?
