Heya I see jitter is a focus on the RT patch.
I was wondering, what settings in features.h gives the least jitter? (I 
am a real perfectionist)
Also what kind of threadpriorities gives the least jitter, particulary 
with a focus on OpenGL? (Should some kernelthreads be reniced, for 
instance softirqs etc)
And have you given consideration to the fact that most distros and OS 
grow with some levels of bloat, and everyone can`t be an expert, so 
maybe one shold consider a (scheduler) queue for "bloat", and one queue 
for main app, so that even bloated distros can run with the jitteramount 
of a highly specialized distro? (for instance 
mainapp,service1,mainapp,service2,mainapp,service3), if bloat is on 
queue 2. Or is thins kind of thinking already in batch, or idle?
