About asyncio debug mode, if it's too expensive to be used to develop an application, maybe there is an issue with additional checks? Should we remove some of them to be able to use asyncio debug mode in more cases? Well, I'm sure some people like them, otherwise they wouldn't have been added to the codebase in the first place :-) For example, knowing where a Future was created can make debug logs much more informative.

The most expensive part of asyncio debug mode is the code to extracts the current stack when a coroutine or a handle is created.

Would it make sense to modify asyncio debug mode to skip the traceback by default, but add a second debug level which extracts the traceback?
