Hi Mike,
Thanks for your help in testing. I've posted a slightly revised patch that should be a little more effective.
I've been running tests using scripts that spawn 100's of processes simulataneous with large greps and finds, and the defragging action is effective much of the time. It depends a lot though on the memory usage pattern -- the current defragger is only able to steal from page and buffer cache. Once I teach it how to steal other kinds of memory it will probably work a lot better.
Regards, Bill
