I am anything BUT a super experienced Python programmer, but if it were my problem - and if BossCmd has anything like an event loop in it, then certainly one way to handle this would be to have a Status.py module that contained status flags for each of the modules.  All three modules would "import status” and do_done and do_exit would set status flags in status.py on their way out.

I’m sure there are better answers.  I’ll be interested to see what else is suggested.
