Actually Andrew Dickson <whydna@...dna.net> came up with this idea
quite a while ago: Keep the rehash interval but do nothing until
some chain hits a specified length.  This is quite similar to
what is being discussed here.

Andrew, could you post the patch please?

In addition to this, we should probably enforce that limit as
well by simply not adding the newly created entry or deleting
one forcibly.

Thanks,
