> Dynamic resizing would be useful. The simplest way to achieve this is to have 
> separate address spaces for each hash function, so that we may 
> increase/decrease accuracy by simply loading/unloading another function (we 
> could even do interesting stuff in future like alternating the functions we 
> select if we find we're getting more false positives than should be expected);
> Faster loading/unloading would help this, and we could achieve this by 
> mmapping the bloom filter representation on systems that we can mlock.
