[ltp] Mandrake 9.1/Redhat 9.0

[Tod Harter]

I guess its 'mini-preemption' then. To be honest I haven't closely followed 
the various branches that real time stuff has taken lately in the kernel, its 
getting a bit too complex to follow... 

I guess what I was saying is that RH has SOME sort of preemption, which is 
mainly aimed at improving multi-media and GUI responsiveness. I guess 
Mandrake slipped that into the 9.1 patch set as well, I didn't notice. I will 
say this much, in 9.1 on my desktop box XMMS has major problems with dropouts 
if you do anything at all in KDE, so whatever that patch is doing, its not 
completely effective (or else there are some crappy video/audio drivers 
around, which wouldn't surprise me in the least).
