generic solution for access to rt scheduling).

If the rt patch does not catch up fast enough then I may need to run a <
2.6.31 kernel (whatever is available at the time) in Fedora 12 when it
is released, hardly a legacy distro :-)

(maybe unlikely, but it would not be the first time rt development
stalls for a looong time and you can't run the latest and greatest - not
complaining, just a fact)

We should try to find out what happens in Jack's case.

It would be a __MAJOR__ step back if RealtimeKit is not usable by Jack
and it becomes the way distributions (and in particular Fedora) give
out-of-the-box access to rt scheduling.
