I thought we had it closed :)
I have not tried with anything past 2.6.26.
2.6.26 as discussed before on this bug has two problems:
1. Counterintuitive use of the word "borrow" in the stats.
2. Bad estimator precision compared to 2.6.18 and older kernels.
If you know about both you can workaround. I do not believe that the use
of "Borrow" will be changed any time soon. It will be interesting to see
if the timers have improved, but I have no test rig to test it right now.
