Ctrl-c now goes through. Thanks!

Exiting the linux instance says "reboot: Restarting system\nUnauthorized
access" and then hangs eating 100% cpu, but maybe I can fix that with
kernel configuration changes.

(I'm still doing a variant of
https://landley.net/aboriginal/control-images so the virtual system
needs to be able to indicate when it's done. But
https://landley.net/aboriginal/about.html is getting replaced with
https://github.com/landley/mkroot so there's some plumbing to do before
that's blocking anything...)

Thanks again,
