> RAMDirectory uses RAMFiles to store the data. RAMFile offers a newBuffer()
> method for extensions to override and allocate buffers differently, from e.g.
> a pool or something. However, RAMDirectory always allocates RAMFile and
> doesn't allow allocating a RAMFile extension, which makes RAMFile.newBuffer()
> unusable.
> I think we can simply introduce a newRAMFile() method on RAMDirectory and
> make the RAMFiles map protected, and it will allow really extending RAMDir.
> I will post a patch later.
