--- Comment #1 from Gordon Hartley <gro.dsbeerf.sgub at gordonhartley.com> ---
I think this needs the 'importance'/severity needs major escalation because
I've had it kill ssh sessions where I couldn't complete backups via scp, and
it's killing the ssh session I'm su'd in when trying to understand the problem.

This has the potential to be one of those 'affects some people' that may
transform into a case that takes out a massive amount of infrastructure that
everyone depends on, and you can't remote in to solve the problem type
scenarios...

The result of this problem could be catastrophic in the wrong environment. 

My fear would be people upgrade production. Everything appears to be running
smoothly for while, so safety is assumed, then whatever scenario that triggers
this behaviour occurs and you can't remote in to save the system, because the
system keeps killing processes involving humans trying to save the system from
itself because the system veto's resource allocation for itself.
