Actually, the documentation is better than I remember it to be. The  
problem is that subclassing is a much more intimate interface between  
components that a call interface.  In the case of asyncore, the  
methods being overridden have non-trivial default implementations.  
Overriding methods often entails studying the base-class code to get  
an idea how it should be done. The subclassing interface for asynchat  
appears to be much cleaner, but even then, you need to study the base  
class code to make sure you haven't accidentally overridden any base  
class attributes.  I wish classes that exposed subclassing interfaces  
were more careful with their internal names.
