Loggers and reloads

You're completely right, thank you. There's always only one logger 
object in my code, however, each time the module is reloaded, a new 
handler is added. Therefore, something like:

for h in logger.handlers:
	logger.removeHandler(h)

indeed does the trick if I put it before the logger.addHandler() call.

Thanks again.
