That sounds like a good solution.  I certainly don't want to cause a 
regression for your customers where this change would cause the OOM killer

I'd like an ack from Christoph on my posted patch that does this before 
it's merged, however, to make sure he thinks its worth the addition of yet 
another cpuset flag.

Thanks for the reviews.
