I just tested this, and it seems to work ok.

Kristian,
Thank you for looking into this!
I will look how we can backport your changes.
We need to have xtradb compiled against standard 5.1, if it is not
broken - it should be not problem to include your fixes.
Thanks!

Kristian,
Ok, thank you.
Please let me know if some code changes required from our side!

Kristian,
Uh, Thank you for looking into this.
You ask good question re: INNODB_RW_LOCKS_USE_ATOMICS, this is actually
one of main points of XtraDB to improve scalability on 8CPU+ boxes, so
