Well, it's possible that you could configure handlers in the configuration for later use (i.e. at some point after the dictConfig() call returns).

If you want to avoid opening the file until it's actually needed, you can specify delay=True, and then you shouldn't see the resource leak because the stream will be opened when it's actually needed.

Unless there's some reason you can't do that, or there's something I've overlooked, I think I should close this as invalid.
