Confirmed this only occurs with Counters.  There is a limitation on deleting 
counters, that they may appear if they haven't been applied to all nodes and 
compacted away.  Not sure if this falls under the same limitation, since in a 
traditional RDBMS, the semantics for truncate are different from delete.
