- Create SingleInstance class to handling single instance stuff. - Instead of calling getInstance() everywhere, initialize each object explicitly in order when application starts and getInstance()s do not create instances any more and they merely return the created instances. - Only set initial values in construtor functions __init__(). Move the initialization of context-aware (i.e. things that depend on other things) to separate functions. - Split application creation and initialziation into several steps and them should be called explicitly in the correct order.
