> Fix For: 1.2

>
> Very commonly, people encountering an OOM need to increase their bloom filter
> false positive ratio to reduce memory pressure, since BFs tend to be the
> largest shareholder. It would make sense if we could alleviate the memory
> pressure from BFs with compression while maintaining the FP ratio (at the
> cost of a bit of cpu) that some users have come to expect. One possible
> implementation is at http://code.google.com/p/javaewah/
