I definitely don't like singletons either, but there are some kinds of functionality that are already singletons, like it or not, and when putting a wrapper around them, one is forced to have another singleton. For example, peak.events provides an event-driven wrapper around 'signal' functionality, and it's implemented by a singleton because -- like it or not -- Python's signal handling interface supports only one handler per signal.
