I saw that the ratio of reads to inserts in our hasherv is ~10:1.
So I have added a cache for unihash reads to somewhat off-load the
hashserver. This since it rapidly becomes CPU bound and also that it
is unresponsive during cleanup operations like vacuum. This goes for
the classic sqlite based solution.

We have run this cache in production now with and it seems to do OK
so I would like to share it either as a contribution or an idea for
improvement.
