By froydnj:

I'd suggest allocating (DYNAMIC-EXTENT, perhaps) a buffer into which you can PRODUCE-DIGEST. That avoids allocating SEED and APPLY #'CONCATENATE, which I doubt is particularly fast.

Oh, hm, the loop doesn't just run to (LENGTH POOLS), it has this other exit condition. Is it possible to precompute beforehand?
