This raises the question "what main context"? I'd suggest that GTK
should store the result of g_main_context_get_thread_default() when
gtk_init() is called.
Also, how does the object slot get set? Add it to _constructed for
each object in GTK+? And then we need to patch the bindings to check
for it?
I'm thinking a cleaner solution is to just patch gtk+ like this:
1) Capture the context at gtk_init() time
2) Patch each finalize method that calls thread-unsafe functions (e.g.
libX11) to use g_main_context_invoke (gtk_get_main_context (),
gdk_x11_cursor_real_finalize, object)
The thing to note here is that we don't need to bounce every
g_object_unref(), we just need to ensure the finalizers are run in the
default main context.
