That is not correct. The list of handlers is empty until `basicConfig`
or explicit `addHandler` is called.
This would also seem to imply that there's no way to use an
empty handler list (say, if you want to suppress all logging), because
the root handler will instantiate a handler for you. Is this correct?
No. Consider this:
import logging
logging.root.warning('error message')
No handlers could be found for logger "root"
logging.root.warning('error message')
Note only one warning message.
Ah, right. It is the module-level functions logging.warn(), etc. that invoke
basicConfig() if no handler is present.
