Is there any rationale for changing the heuristic from "fits in a whole number of cachelines" to "allows fast division by the blocksize"? I personally would prefer if such changes were justified a bit more than by a one-liner changeset message without any corresponding open issue.

I share the doubts of Antoine and I was going to write the same comment. I thought there were good reasons for previous code. What has changed?
