Great, thanks for giving pointers on octave. definitely speeds things up
if i know a bit of how to use it :)

I also confirmed it works with the PPA.

1. lxc launch ubuntu-daily:questing && lxc shell $INSTANCE
2. sudo apt-mark hold apparmor (there's a bug in apparmor ATM)
3. sudo apt upgrade
4. sudo apt install octave
5. octave --no-gui
drops into a prompt. Input _generally_ does not work. enter does do a newline (which is interesting, but not important). This behaviour aligns with the event loop issue (if i'm understanding correctly).
6. exit window (cause you won't be able to exit normally :/ )
7. lxc shell & sudo add-apt-repository ppa:jchittum/readlines-lp2118818
8. sudo apt update 
this should bring in libreadline8t64 from the ppa
9. octave --no-gui
typing works! 

i'll put up the git-ubuntu MP and get this merged for questing
