That turns off all swapping and isn't going to answer the question.
Julian's point does seem reasonable - there is a potential problem
relating to swapping kernel threads but there's no clear evidence
that it is or isn't a real problem.  Adding a knob to easily control
the behaviour would be useful - we stand to get some real data and
can then better make a decision as to how to proceed.
