DirectMemoryStore is an implementation of the ehcache store interface for 
directmemory and should try contain all the handling of normal store features,
DirectMemoryCache is to support all features needed from directmemory to 
support the store, and thus to support extra functions/features or changes of 
behaviour for direct memory needed for ehcache integration which we wouldn't 
necessarily want to put into the core, agreed atm this does make this a bit of 
a pass through layer but i can i can see several items already that would want 
specific to ehcache, atm it has two features it is supplying size and capacity 
in bytes of the cache. 

On the MemoryManagerServiceWithAllocationPolicyEhcacheImpl this originally was 
to change behaviour of  MemoryManagerServiceWithAllocationPolicyImpl to throw 
boe instead of what was the current behaviour of returning null, (which 
actually does cause an npe in the cacheservice implementation which probably 
needs to be fixed) , but anyhow, exception behaviour handling allows to wrap 
into ehcache cache exception nicely. Benoit migrated this functionality 
actually into directmemory core so yes agreed this could be removed now. 
(though i would think about leaving it for now maybe, as with like argument for 
the directmemory cache, if there is features we want specific to the ehcache 
integration, that in furture we wouldnt want in the main core, then it is can 
be placed here).
