I'm not sure I understand your questions. Multiple monitor sessions are
like multiple shell sessions. I don't think a control program should
use more than one session, but it should allow a developer to connect to
issue 'info registers' and 'x/20i' commands. Of course if a developer
issues 'quit' or a hotunplug command, things will break.

If we can identify an interactive session, we might redraw the partial
command after the prompt.
btw, why would a human enable notifications? Note notifications enabled
on the management session will only be displayed there.
Do not meddle in the internals of kernels, for they are subtle and quick to panic.
