I would like to see a confirmation from Vinayak that this really helped
in his test case first and only then drop the above patch. I really
think that we shouldn't spread hacks around the code just workaround
inefficiency in the vmstat code. We already have two places which need a
special treatment and who knows how many more will show up later.
Even with this patch applied we have other issues related to the
overloaded workqueues as mentioned earlier but those should be fixed by
a separate fixe(s).
