When we are in the global OOM condition then you are right, we have a
higher chance to panic. I still find the patch an improvement because
encountering a frozen task and looping over it without any progress
(even though there are other tasks that could be killed) is more
probable than having no killable task at all.
On non-NUMA machines there is even not a big chance that somebody would
be able to thaw a task as the system is already on knees.

That's obviously false since we call oom_killer_disable() in 
freeze_processes() to disable the oom killer from ever being called in the 
first place, so this is something you need to resolve with Rafael before 
you cause more machines to panic.
