hi Patryk,

problem with your suggestion is that I'm hever heard of stable release
for fr, now everyone is forced to use kernel several times slower that
it is in real.

i can even hardly undertand this - everyone is talking about slowness of
freerunner, but no one want to just disable debugging features to have
speedup in times.

imo, kernel dev (who are 5% of community) can compile own version to do
development - anyway they need to compile it to do development.

also, preemption cann't help developers anyhow.
