Works for me. I have the premption patch turned on.

On a 192 MB PIII laptop running at 500 MHz I have two X sessions
running, and have opened a zillion application windows on each,
including over a dozen Netscape windows, some Mozilla's, a couple
emacs's, a kernel compile, Staroffice. About every app I can
immediately think of. I haven't tried malloc-ing a ton of memory, but
this contrived real-world test works.

Swap is at 238 MB. Lower than I would have expected, but that doesn't
mean I know anything.

Switching between X sessions just took near 10-seconds going, and only
about 5-seconds coming back. Switching in Staroffice is painful, but
generally the responsiveness feels quite nice.

I like it. Thanks,

patch, plus this patch--once he figures out how to close all those
