To be clear, not only does it not block, dbus_connection_dispatch()
never does any IO (unless the app message handler does).
On the DBusConnection doxygen page I talked a bit about how there are
three operations (read, write, and dispatch) and what they each consist of.
read = fill the incoming queue by reading from socket
write = drain the outgoing queue by writing to socket
dispatch = drain the incoming queue by running app handlers
