I agree, this seems much cleaner than what I've proposed.

In fact, the "ForwardingHandler" idea could be submitted to SourceForge as
a separate patch for logging, and then the issue drops out of this
"consistent logging" PEP altogether.

So that changes my proposal as follows:
- The getdefaultlogger() and setdefaultlogger() functions go away.
- The self.logger attribute of class instances can be initialized to
logging.getLogger(__name__).
- Some kind of "ForwardingHandler" can be added to the module's logger to
forward messages elsewhere in the logging hierarchy.  But this is not
likely to be a common use case.
