[issue30457] Allow retrieve the number of waiters pending for most of the asyncio lock primitives

Not really, your code never removes the key from the events. If the cache is cleaned all further executions will keep forever in the `wait` statement. It is needed to create the Event again to perform at least one query to retrieve the cache value.
