You could achieve that "one and only one" either by having a main
program which creates the instance and pass the reference to each thread
via its __init__ or you implement the Configuration class as a singleton
like this:

Singleton.getInstance().
Singleton.getInstance() is so "javaistic"... :)
Actually there is no need for all of that; just define the RLock at the
global scope in a module.
Don't feel bad by using a "global" name - remember that a Python module
acts as a named singleton. Defining an object at module scope is
equivalent to defining an instance attribute in your Singleton class.
