    @JamesRTaylor I'm seeing the following issue with using indexTableRef.getCurrentTime().
 In my test, if set the index to PENDING_DISABLE.  I then perform a query, which uses the
index as expected.  If I then advance the EnvironmentEdgeManager clock to beyond the threshold,
then perform the query again, it still uses the index because indexTableRef.getCurrentTime()
hasn't changed.  Is this expected?
