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.
