> Bloom filters are currently using the LRU block cache.  They are being 
> treated as normal data blocks, however, it would be advantageous if we could 
> treat me separately and give them their own portion of the LRU.
> What we've seen in practice is that some blooms get very big and are accessed 
> frequently.  This leads to blooms consuming a majority of the cache so lots 
> of churn on data blocks.
> In any case, I think it is desirable in general to be able to control how 
> much memory is used for blooms and other meta data.
