hm, how about the questions Mike raised (there were a couple of cases of
friction between 'the design as documented and announced' and 'the code
as implemented')? As far as i saw they were still largely unanswered -
but let me know if they are all answered and addressed:

http://marc.info/?l=linux-kernel&m=117465220309006&w=2
http://marc.info/?l=linux-kernel&m=117489673929124&w=2
http://marc.info/?l=linux-kernel&m=117489831930240&w=2

and the numbers he posted:

his test conclusion was that under CPU load, RSDL (SD) generally does
not hold up to mainline's interactivity.
