It's sort of "defined" that if you connect to the session bus you're
part of the session and should thus exit with it. (it causes a lot of
problems for sysadmins on multiuser systems if sessions leave leftover
processes; historically the default exit-on-disconnect behavior of
Xlib solved the issue)

This is the right behavior for 99% of apps, that's why it's the default

If you are in the 1% (maybe you aren't in the session, just "peeking"
at it) then get_private is probably totally correct to use. It's not
_that_ much memory.
