    Since signals are run synchronously (i.e. they are not deffered to
the main loop as events, as some tend to imagine) they are always the
result of the signal's object being accessed, so if the object is a gdk
or gtk object; then the lock must be aquired first (making those signal
callbacks run inside the lock).
