There is an admonition in the Pickaxe book that says "In both the class 
form and when including MonitorMixin in an existing class it is 
essential to invoke super in the class's initialize method."

I want my sychronization to occur in a class method.  So that would seem 
to obviate the need for the super in the "initialize" block.  Am I 
correct?

Thanks,
Wes
