 The change was not deliberate but there have been some other people report 
 significant changes in the swappiness behaviour as well (see archives). It 
 has usually been of the increased swapping variety lately. It has been 
 annoying enough to the bleeding edge desktop users for a swag of out-of-tree 
 hacks to start appearing (like mine).

All of which is largely wasted effort.  It would be much more useful to get
down and identify which patch actually caused the behavioural change.

I don't disagree. Is there anyone who has the time and is willing to do the 
regression testing? This is a general appeal to the mailing list.

Cheers,
Con
