If you do, please remember this report. Quick summary: All problem areas I've seen are completely resolved - or at least to a major extent. Blender, wine and "cp -a".
Andrew Mortons red flag was a good incentive to run my tests on a pure 2.6.0-test4 and write down the outcome. Adding the O18.1int after this really stand out.
I won't repeat all my hardware or software facts, but thought I'd add a few words on tweaks that might have influence: File system is ext2 with all partitions mounted "noatime". Disk readahead has been upped by "hdparm -a 512". VM swappiness reduced to 50 (I've got 128 meg mem). /dev/rtc is changed to 666, read/write for everybody, and /proc/sys/dev/rtc/max-user-freq is at 1024.
*** _The game "Baldurs Gate I" under winex 3.1_
2.6.0-test4: Loads but is seriously starved. Sound repeats and graphic freezes occur with a wave-like frequency. Mouse pointer can hardly be controlled. Playability 0 of 10.
2.6.0-test4-O18.1int: Not starved for most of the time, and I can not cause "priority inversion" on demand with my usual tricks. There _are_ random freezes but the game recovers within 2 seconds. Playability 8. ***
*** _Blender 2.23 (standalone, and xmms 1.2.7 on a directory of mp3s)_
2.6.0-test4: Doing a slow "world plane" rotate around the axes is in perfect sync. No freezes (and no music skips).
2.6.0-test4-O18.1int: The same as vanilla -test4. ***
*** _Blender 2.28_
2.6.0-test4: The slow "world plane" rotate cause a 2 to 5 second freeze, quickly repeating itself if I continue the rotate. Mouse pointer can become invisible, freeze or jerk right across the screen while loosing its grip of the world plane grid.
2.6.0-test4-O18.1int: Perfect sync! How did you achieve this Con? No matter how long I do the slow "world plane" rotate I can not get it to freeze. Same with a quick rotate. ***
*** _Blender 2.28 plus xmms 1.2.7_
2.6.0-test4: Short blackout, ca 3 seconds, at the beginning of a new song if I starve xmms with the slow "world plane" rotate. Not during the song, only at the beginning.
2.6.0-test4-O18.1int: Music perfect during any rotation. Both beginning of songs and the rest. ***
*** _"cp -a" of /usr from hda to hdc and using Opera 6.12 "software scrollwheel" on svt.se (page has 70+ small graphics) or a long slashdot.org comment page_
2.6.0-test4: "cp" PRI is 15-16, Opera PRI is 15. Slight jerk every 5 second while scrolling the page on lowest speed.
2.6.0-test4-O18.1int: "cp" PRI is 17-18, Opera PRI is 15. Perfect smoothness while scrolling. ***
