I recognized that some core tools like dbus-monitor uses the glib 
mainloop. What does this means relating to the binding split from the 
core ?
If glib will be a requirement for the core library, than on windows glib 
will be a requirement for dbus, which would not be good at all.
If glib will not be a requirement, a dbus only mainloop has to be 
implemented for unix and windows.
