Can anyone explain whether there's a direct relationship between the  
"singleton" in "singleton pattern" and the "singleton" in "singleton  
class"? I mean, does the singleton class implement the singleton  
pattern somehow (I am not aware of any instance of the singleton  
class) and hence the name? Or is "singleton" there used just because  
of the meaning it conveys to the class, so to speak, and not because  
of the pattern?
