	Last time I looked at GDK_THREADS_ENTER / LEAVE it's performance
depended on whether the (global) gdk_threads_mutex was non NULL; of
course - that would need initialising at some stage; whether that can be
done idly / in a delayed fashion - I don't know - prolly difficult.

	More difficult I think, is the necessity to do different locking
primitives for the same method call when called from different places -
[ inside / outside main-loops etc. ]. I think the Gtk+ design is quite
unhelpful there, but perhaps that got fixed - I know not.
