your almost setting your kernel up like you plan on doing audio work.

After setting the SCHED_IDLEPRIO flag on F at H, it is completely unnoticeable no matter what else I run. This is how a desktop should be. The only downside is that the system uses about 20% more power at idle (without CnQ + C1E). However, since I fold 24/7, it's never idle anyway.
It's sounds like your problem, wasn't even Wine related, and that you
were having kernel and priority issues.
The power consumption is a bit wierd, as i do not experience that,
from those patch sets.
I use the BFS patchset, as it is included in Zen-kernel
(www.zen-kernel.org). you should check it out. you can also setup
"schedtools" with SCHED_ISO applied to X by default, right in the
.config (menuconfig). You may also find that certain applications
will benefit from using SCHED_ISO. Examples would be
Jack-audio-connection-kit, I use it with "mypaint" and any Wine
application that seems to not be keeping up.
it keeps everything nice and smooth.
