> Sometimes an entry set for eviction will remain in the region map after 
> falling into an unhandled case in RegionMapDestroy.retryRemoveWithTombstone. 
> When testing the LRU capacity of a region, we create many entries beyond the 
> LRU capacity, causing evictions. We sometimes run into a case where two 
> threads compete to remove the same entry. One thread succeeds and removes it 
> from the region map, while the other thread, in removal progress, will create 
> a temporary entry in the map that does not get properly removed/handled.
