I didn't have time to personally test it but just want to share some thoughts. 
This kind of improvement is absolutely necessary for 2.6 to be usefull on the 
desktop. It continues to escape me how come that this kind of, almost, bugfix 
arrives so late during stable period.

Unfortunately it doesn't apply on top of Con's autoregulate swappines (AM from 
now on) which I am currently testing. AM also does an excellent job in 
preventing swap trashing while doing a lot of filesystem reading.

I am curious on how does your patch technically relates to Con's AM, and is it 
possible to merge the two? I know that they do their job on completely 
different ways, so the real question would be: Is there a need for something 
like AM if using your patch, or it completely obsoletes it?
