Pekka,

This is a good thing to have - any background on your choice of
terminology? glib calls this a "weak pointer" -
http://developer.gnome.org/gobject/stable/gobject-The-Base-Object-Type.html#g-object-add-weak-pointer

Cheerio,

Rob

PS: The reason I ask is for me "guard" is more like something like
g_return_if_fail etc.
