[issue39198] Lock may not be released in Logger.isEnabledFor

[Derek Brown]

New submission from Derek Brown :

If an exception were to be thrown in a particular block of code (say, by 
asyncio timeouts or stopit) within the `isEnabledFor` function of `logging`, 
the `logging` global lock may not be released appropriately, resulting in 
deadlock.
