One of the theories that has been advanced is that it's simply this
problem:

	http://lkml.org/lkml/2010/5/22/154

If so, it points out how idiotic Phoronix is about not being able to
notice udev pegging the CPU at 100% being someone bad for its
benchmark runs.  :-)

OTOH, this bug has been known for over a week, and it is sort sad that
we haven't reverted this patch.  It looks like the conversation has
died, but without a fix?
