Michal, unfortunately i had to boot to another kernel because the one with this patch keeps killing my MySQL server :( it was, probably, doing it on OOM in any cgroup - looks like OOM was not choosing processes only from cgroup which is out of memory. Here is the log from syslog: http://www.watchdog.sk/lkml/oom_mysqld

Maybe i should mention that MySQL server has it's own cgroup (called 'mysql') but with no limits to any resources.
