Maybe you should play around a little with /proc/sys/vm/swapctl
and /proc/sys/vm/freepages...
A 1:2:4 ratio for freepages usualy works wonders.
And a echo "10 3 1 3 0 0 0 0 1024" > swapctl gives some
improvement too. As a matter of fact, I'm currently (read:
now) removing some of the 1.1.xx artifacts from mm/vmscan.c...

Things will straighten up RSN, but until that time, you can:
- tune /proc/sys/vm/*
- tune mm/vmscan.c (just make it more agressive)

The main reason that you didn't get that message with the
old kernel is that it doesn't show you the error, but
you're right, I should limit the printout of the error
(to once every 5 seconds?).
