I've just tried with 100M hashes (raw-md5 of numbers 0 to 99999999), and
no.  It's 1:18 on that machine either way.  For the 29M, benchmarking
just the loading now gives me a little over 21 seconds either way.
Maybe there's an improvement from 21.7 to 21.3 or so, but that's very
little.

I think it's a failed experiment for now.  I still think something like
this can be done for a speedup, but not exactly this.
