Do any other controllers do something like this?  It seems odd.

Maybe not in sense of killing something. My understanding memory.reclaim does not necessarily invoke the OOM killer. But what I really intend to say is we can have a separate knob for user to express the need for reducing the current usage explicitly and keep "misc.max' non-preemptive semantics intact. When we implement that new knob, then we can define what kind of reclaim for that. Depending on vEPC implementation, it may or may not involve killing VMs. But at least that semantics will be explicit for user.
