What about results with latest -aa kernels?
I'm writing this letter while running your killer-test ;)
My machine is perfectly responsive.

$ uname -a
Linux localhost 2.4.19-pre6vm33 #2 Sat Apr 13 00:56:55 MSD 2002 i686 unknown
This is vanilla 2.4.19-pre6 + vm33 from Andrea Arcangelly.

Funny stats:

bash-2.05$ free
total used free shared buffers cached
Mem: 516496 512804 3692 0 2080 10064
-/+ buffers/cache: 500660 15836
Swap: 1028120 1028120 0

I'm running X, netscape, mutt, top, 5 xterms, web, mysql, ftp, samba etc.
Lots of "0-order allocation failed" in the log. Anyway it is usable!
The good thing is VM is killing right process most of the time:

VM: killing process memory-killer

Netscape got killed. Big deal, I can start it again and it works...

P.S. Running it already for 20 minutes.
