Feel free to ask if you have a question in my code.

But, basically, the main loop boils down to:

- a central place that does select(2) on all sockets
- when the D-BUS socket is activated for read, the binding calls 
dbus_watch_handle and then dbus_connection_dispatch (as long as 
- when the socket is activated for writing, we just call dbus_watch_handle

There are some other callbacks like the timers: the select(2) call is 
limited on timeout on the shortest timer pending.
