    incorrect comment?  we are not returning an INVALID token but rather an 
empty string?  Should we use a static string for this?

> We're seeing issues where the data in the lucene index does not match the 
> data in a region. Here's what I see happening
> # An accessor starts doing a put
> # The put goes to the current primary
> # Primary distributes the put to the secondary
> # Primary closes it's cache
> # New primary does a destroy on the same entry
> # The accessor retries the put because the old primary closed the cache
> # The retried put is added to the queue, after the destroy. But it is not 
> added to the region, because the region detects that it is a retry.
> # The lucene index applies the put. Now there is an extra entry in the index 
> that is not in the region.
