Changing settings from 64 frames per period to 128 reduced, but didn't 
eliminate the xruns, while 512 seemingly did (still tested "idle", no 
audio playing or recording).

I already deleted the generic kernel from my system because it sent jack 
on strike. Lots of error messages on startup and music players freezing 
playback if I tried to use jack sink and source. I didn't try with 
higher latency, though.

I'm not going to try again, either, being on my way to start meddling 
with 13.04, I'll focus the trial and error on the 3.8 branch...

Thank you very much for constructive and helpful input!
