I find 2.1.131 to be much better than its recent predecessors in
terms of reduced swap activity with the same set of applications
loaded (X, XEmacs, netscape). Pages are staying in memory when
they used to be swapped in and out all the time. Whatever
changed between 2.1.130 and 2.1.131 was hardly any sort of
mistake, as far as I'm concerned.
