I just ran netscape which for some reason or another went totally
whacky and gobbled RAM. It has done this before and made the box
totally unuseable in 2.2.17-2.2.19 befor the kernel killed 90% of
my running apps before getting the right one. This time, it
OOM'd and killed Netscape and I got control back instantly. This
is with 2.4.2. I hope this is a good sign!

Maybe, but 2.4.2 and 2.4.3 are still using the "old" killer algorithms
which can behave erratically. I haven't looked at 2.2.x OOM killers at
all, so I don't know how they compare. At some point in the near future, I
want to separate my patches out so they can receive individual attention
and hopefully get applied.
BTW, on this subject, if anyone sent me a mail which I haven't replied to,
I probably never got it due to e-mail problems with my ISP. If it's still
relevant, please resend.

I ported the 2.4 OOM killer about half year ago to 2.2, available for
2.2.19 kernel at
http://mlf.linux.rulez.org/mlf/ezaz/reserved_root_memory.html
Note, since it's activated in page fault handler that is architecture
dependent, the current patch works only on x86 (the only one I could
test). If one is interested in other archs, let me know.
