 If a couple of threads then call <code>get_instance</code>, the first thread

 ## The bug
 
 Unfortunately, matters became a bit more complicated when I tried to have two
 singleton classes.

+I had `Logger`, like in the example above, and some kind of a "master"
+singleton (let's call it `Duke`).
 These two classes both inherited from `Singleton`, which I thought was nice.
 `Duke`s constructor was heavy and complicated and definetely required some
 logging to be done.
