Description
In bug 647419 I'm planning to call g_settings_sync() from the end of g_application_run(). I'd like to be able to do the same for GDBus.
The problem is that the existing flush() API requires me to specify the connection that I want to flush and I don't know how to get a list of all open connections. Certainly it would be quite a mistake to request the system and session bus for purpose of flushing them because they might not already exist.
