Ubuntu security update to kernel

After applying this kernel patch I see some 20-40 second delays (estimated) in a couple couple if KDE applications [1](repeatable use cases).

Looking at the changelog I'd guess some futex related operation might be timing out before the applicatio continues. Does the futex patch also affect non-attack-usage of futexes (maybe slightly bad programming?)

[1] Yes, I know Lucid is only supported for servers anymore these days, not UIs, no heads up required in that respect. Upgrading has been on the way for a while...
