itemsize isn't part of the interface. I'm not sure it could be added, since we may have variable-width EAs.

Probably want to add a docstring for your Int*Dtype.itemsize, since once won't be inherited.

LGTM otherwise.

[jreback]

not sure why azure is not running on the personal builds. but this is ready @TomAugspurger

[TomAugspurger]

Agreed. We may want to hold off on merging larger changes, since I believe linting is now on azure, but this LGTM.

[TomAugspurger]

But let's see if it runs for the merge build. If so, then we can merge things and followup as needed.
