I'm not sure how you reach that conclusion: it's necessary because any 
process handling the oom condition will need memory to do anything useful.  
How else would a process that is handling a system oom condition, for 
example, be able to obtain a list of processes, check memory usage, issue 
a kill, do any logging, collect heap or smaps samples, or signal processes 
to throttle incoming requests without having access to memory itself?  The 
system is oom.

This is going to be discussed at the LSF/mm conference, I believe it would 
be helpful to have an actual complete patchset proposed so that it can be 
discussed properly.  I feel no need to refer to an older patchset that 
would not apply and did not include all the support necessary for handling 
oom conditions.
