Agreed. I have to think it's a coincidence I'm running vmpatch2.

vmstat look the same, but here's some timings of bunzip'ing the kernel
source into a file (notice pagefaults and swaps):

This is under 2.2.16-9mdk:
31.50 user 1.17 system 0:34.68 elapsed 94%CPU
(0avgtext+0avgdata 0maxresident)k

This is under 2.4.0-test7-vmpatch2b:
265.58 user 8.91 system 5:18.06 elapsed 86%CPU
(0avgtext+0avgdata 0maxresident)k

Your eyes are weary from staring at the CRT. You feel sleepy. Notice how
restful it is to watch the cursor blink. Close your eyes. The opinions
stated above are yours. You cannot imagine why you ever felt otherwise.
