I wrote a demo for GtkD showing how multi-threading and D work 
together, it's in the demos/gtkD/DemoMultithread folder of GtkD, 
hopefully it will be helpful. However this example it is based on 
using the GTk threadIdle callback which is generally preferred 
over the locking methods you show above, obviously though your 
use case may vary but keep in mind the locking methods have been 
deprecated, see the GTK 3 reference manual here:

https://developer.gnome.org/gdk3/stable/gdk3-Threads.html

You also see this GtkD issue here for 
https://github.com/gtkd-developers/GtkD/issues/137 for some code 
on how to use Delgates with gdk_threads_add_idle (i.e. GtkD 
gdk.Threads.threadsAddIdle).
