One new question, hopefully this one is just rote arcana to one of you....

The current scheduler strategy always tries to place a given periodic
request (be it iso or intr) into the same uFrame slot in all scheduled
HFrames.  Is this a requirement of the spec (I don't recall seeing
such a restriction) or merely convenient to the current code?  In some
ways it's easier to just stack requests into the full-speed frame and
then plop the splits into whatever uFrame that happens to work out to,
even if that means that, eg, an interval 1 iso request might be
serviced in substantially different portions of the actual full-speed
frame.

Perhaps the latest iteration of rereading the specs again will yield
yet another new layer of understanding ;-)  The corner cases are
looking less and less scary with each pass; the logic all feels
intuitive at this point.
