If an exception were to be thrown in `Logger.isEnabledFor` (say, by asyncio

timeouts or stopit) , the `logging` global lock may not be released

A change was made to logging.config.dictConfig to avoid converting instances
|
||||
of named tuples to ConvertingTuple. It's assumed that named tuples are too

specialised to be treated like ordinary tuples; if a user of named tuples
|

requires ConvertingTuple functionality, they will have to implement that

themselves in their named tuple class.
