There is actually a fairly simple solution; add an API to
org.freedesktop.DBus to explicitly opt-out of being disconnected on
session end.  Then if we make the "session bus" really "user-machine
bus", things like pulseaudio could stay around if there's another
session holding the usermachine bus open.
