Oh, and here comes lapwing:

- regression_slot |          1 |          12
+ regression_slot |          1 |          10

So if it weren't that prairiedog showed 11 not 10, we'd have a nice
neat it-depends-on-MAXALIGN theory.  As is, I'm not sure what all
is affecting it, though MAXALIGN sure seems to be a component.

(locust seems to be AWOL at the moment, so I'm not holding my breath
for that one to report in.)
