The launchpap link suggest that the leak does not appear in 2.6.33, only in 2.6.32. That may mean a fix may miss in 2.6.32 longterm branch or that some different interaction in 2.6.33 make that issue disappear. I may try to look at git log changes from 2.6.32 to 2.6.33. Unsure I could find a pin in this byte forrest.
