Well... if Ingo is amenable to the arch hook in the scheduler, I'm
OK with changing directions. Again. :-)

The arch hook would be a lot simpler this time -- simply setting
a flag instead of performing the PIO write drain. Not sure if
that's enough to argue in favor of the hook or not.

Truth be told, I have no strong preference either way. I'd just
like to break out of this Brownian motion. :-)
