OK, I'll recheck bug in squeeze and report it separately.

Main problem for this bug is very high value of free memory when OOM
killer starts. In my tests it appear when about 300MiB was free. And it
kill not most 'badness' process, but runs repeatedly for few (or even
all) process. 

But, again, I'll recheck it in clean environment with reproducible
behavior and submit it.
