I didn't succeed at getting something postable.  :(  I could easily
repost some of the earlier patches (like fixing aligned memory, etc)
if there's a desire for those, but I figured I'd wait until I had
something postable for the microframe scheduler.

I've definitely made progress in the last few days and things are a
bit cleaner at <https://chromium-review.googlesource.com/#/c/313808/3>.
It's also working reasonably well, but I'd still like to understand
some of the behavior I'm seeing before I actually post it to the
mailing list.

I'm going to be away from my computer for about a week, so I'll plan
to pick this up again when I'm back...
