You've taught me a lot in the snippage above, but you skipped a key question: 

What do modern sysadmins in  datacenter environments want their machines to 
do when overloaded? The overloads could be malign or benign, they might even 
be profitable. In the old days the rule seemed to be "slow down if you must, 
but don't stop". Page first, swap second, kill third. 

Has that changed? Perhaps the jobs aborted by OOMA can be restarted by another
machine in the cloud? Then OOMA makes a great deal more sense.

Thanks for reading!
