== Summary ==
Install earlyoom package, and enable it by default. This will cause
the kernel oomkiller to trigger sooner, but will not affect which
process it chooses to kill off. The idea is to recover from out of
memory situations sooner, rather than the typical complete system hang
in which the user has no other choice but to force power off.

I've read the whole thread (phew!) and I support the proposal. The user experience is improved and I don't see any substantial disadvantages (power management etc can hopefully be fine-tuned). Of course the code should be well inspected by someone knowledgeable, if it's going to run with high privileges. And if there are serious candidates with a better approach (e.g. something from systemd), it might make sense to delay this and wait a while. OTOH, if verifying the code and setting it up is not that much work, those candidates can replace early-oom in the future, and no delay is necessary. Overall +1 from me.
