Well, this makes a difference. I filled up my memory with something else 
before starting mystress.pl because of top's|ps' slowness with many processes.
I had about 400 processes. The test from yesterday had ~ 1800.

With your patch, mystress.pl was marked to get killed, every PID only once, no 
apache or similar (good). ... But the strange thing is, that it seems none of 
the processes, which are marked to be killed, get killed. So sysrq-t tells 
me. Sysrq-i gave me the chance to get out of the OOM killing process and only 
kernel threads were left + getty's so I was able to log in again.
