The problem would disappear if you wrote a small testscript that uses your
module and execeted that from scratch, instead of reloading the module -
which might also create other state related problems.

But if you insist on using your module, you could place the logger
initialization into another module or encapsulate it in a function that you
call manually - but only once. As the logging systems state is kept in the
not-reloaded logging module, that should rid you of your problem. I bet it
would also be possible to check if for a given logger already a handler is
registered, and refuse to add another one.
