I plan to, but I got a little side tracked. We need to ensure all
schedule() callers can deal with spurious wakeups. To that end I talked
to the smatch author who kindly provided a test for this, but I still
need to actually run it and see how bad the fallout is and fix stuff up.

All core primitives 'should' be good, but there's a lot of shady stuff
out there that isn't.
