to test the oom killer you should try to run out of memory sometime.
It's not the oom killer that cured the oom faliures, it is the deadlock
prone infinite loop in the allocator that did.

Now I identified various issues that can explain the oom faliures on the
highmem boxes (I don't have any highmem box so it wasn't possible to
trigger them here, the higher memory ia32 machine that I own is my
UP desktop with 512mbyte of ram), and I will be able to verify my fixes
as soon as I can get a login on a 4/8G box. I created this project for
this purpose:

	http://www.osdlab.org/cgi-bin/eidetic.cgi?command=display&modulename=projects&on=60

After I get the login and after verifying my fixes I'll release a new
-aa that will be meant primarly to fix the allocation faliures.
