Still outstanding. Andrew said he was going to send the patch to Linus, so
I hope it will be fixed for 2.6.32-final.

yes It's still there.. I'm wondering because
there's not much feedback on this maybe I should take
a hint! or maybe it's something people just don't
understand, and don't have time for.. In any case
I'm still looking at it(although had to look at other
reports as well).
