So under high load I can generally cause a freeze in Gnome/Ubuntu. This
is somewhat expected and likely should be fixed by some sort of OOM
killer. However that's only part of the problem. Virtual Consoles are
disabled (`/etc/systemd/logind.conf` `NAutoVTs` by default) and I
believe that too to be a bug. In the past I could have Switched VT's
logged in and killed of a high memory/cpu process or two. Now I have to
hard kill the box and risk loosing in progress work which is ungainly.
If there's a worry about "what will new users do if they accidentally
hit CTRL+ALT+F\d" maybe instead of disabling it we could change the
default login message to have a "Don't know how you got here? Hit
CTLR+ALT+F1 to go back."
Also because I have to hard restart apport never get's called to show
exactly why the system is hanging.
