We really should decrease the borrow percentages for buffer
and page cache down to 15%, or do a compulsary switch of
methods when we've performed our trick a certain number
of times...
I've experienced the mega-swapouts as well, but due to
my own patch doing swapIN readahead they didn't feel
that bad :)
