What is really needed is an separate "multimedia scheduler" system
within the kernel. This is mentioned in Linas Vepstas' paper on how to
properly design high-performance graphics systems:

NOTE: The GGI web pages contain an old version of this document,
which is about half the length of the version on Linas' site and is
missing lots of important info. Marcus, could you replace the outdated
local copy with a link to the new version on Linas' page?
