Well, last time I checked, with the patch compiling peval.scm was 2.10
seconds, compared to 2.35 without. Not tiny, not huge.

No I did not. Another thing one could fiddle with would be the block
size for a new list head. I feel like we need more metrics though: a
distribution of sizes of blocks, numbers of blocks in a vlist, hash
collisions per block, etc. I'll merge this to master soon and we can
check what impact the new hash function has on performance.
