Hmm, seeing functions I wrote in diffprofiles like this gives me the
wli's. Any chance you could snapshot /proc/slabinfo say every 1s during
a run so I can see what's going on?

You should be able to recreate this easily yourself, but on closer
inspection, it seems the cost is just shifted from pgd_ctor.
