"While the cheat attack is simple, to our knowledge, there is no published
record of it, nor any mention of it on the web. Related publications point
out that general-purpose CPU accounting might be inaccurate, but never
raise the possibility that this can be maliciously exploited."

"From the seven OS/scheduler pairs we have examined, only Mac OS X was
found to be immune from the cheat attack."

Will Leopard be similarly immune?

Requested and noticeable "performance improvements" are reported as a
reason linux became more vulnerable from 2.4 to the 2.6 kernel.
