> Near-Real-Time Lucene usage requires a coupling between the indexwriter and the indexreaders being used for searches.
> Also to make other features simpler we need to manage indexwriters and indexreaders in a more integrated form (Infinispan).
> refactor : DirectoryProvider
>     * make a "DirectoryManager" instead, which is able to provide factories for both IndexReader an IndexWriters
>     * add utility methods like "getName()"
>           o (wish I had that in some cases to provide better error messages)
>     * Instead of trying to foresee all needed methods, the extension point should not be the DirectoryManager interface directly, but have people plug in different aspects.
>     * This is needed to eventually support:
>           o Instantiated indexes - HSEARCH-336
>           o make good use of all new so called "Near-Real-Time" Lucene improvements by having IndexReader and IndexWriter possibly generated by the same service
>           o reuse the JGroups channel used by the Infinispan Directory as transport for a backend (again, the two components need to interact)
