The basicConfig sets the root (or "") logger, any messages from other 
loggers will end in the root logger if the propagation setting is enabled.

There is the misconception that with the logging module you could have 
completely different loggers. In reality there is only 'one' logger, but 
with the hierarchy of names and some logic you could use as if there is 
more than one logger.

Also in your propose the name of getLoggerReader is misleading as this 
implies that there is something to read, there is not, a log event is 
something to process, write if you wish (this is the purpose of handlers).
