BB#110 Increase number of hash buckets from 32 to 256.

This should make hash processing generally faster.

There is a treadeoff between memory footprint and
speed of processing. 10 KB instead of 1.2 KB of
hash table per process should not be a huge problem
even on very limited current systems.

Who really needs to stick to 32 buckets could
recompile. We could also think about making
this configurable at some point.
