/me giggles like a 12 year old girl (teehee)

Try an earlier version of blender and you'll see it goes away. Other ones to
try are opening a gpg signed mail (like this mail) in kmail. The slower the
sleep avg decay in any tree the longer the spin. Nick's changes I believe
cover up the flaw. I'm not discounting Nick's work, but I do believe the apps
are broken and it's only the current scheduler design that makes it visible.
I would also like to make it impossible for priority inversion to happen but
at the moment I've just got to make sure they dont starve anything but their
dependent cpu hog. Still looking for some useful task dependency tracking.
