Called by lower levels {@link AbstractRegionMap} while holding the entry synchronization
<bold>and</bold> while the entry remains in the map. Once the entry is removed from the map,
then other operations synchronize on a new entry, allow for ordering problems between
{@link #create(Object, Object, Object)} and {@link #destroy(Object, Object)} operations.

@param entry the Region entry being destroyed
@param event the event describing the destroy operation
