Until there is an instant, or nearly instant, scheduling algorithm,
there will always be some lookout periods where scheduling requrests
are deferred.  I would like to return a monotonically, increasing ID
with all schedule requests.  Frontends can then display some sort of
busy indication until that ID or a later one has been serviced.  I
don't know when I'll get to that.  Patches welcome.

needs attention.  Please open a ticket and describe in detail how to
reproduce the problem.  Especially include what pre-roll setting you
use and the state of the inputs immediately before and after the
problem occurs.
