[issue41435] Allow to retrieve ongoing exception handled by every threads

[Julien Danjou]

New submission from Julien Danjou <julien at danjou.info>:

In order to do statistical profiling on raised exception, having the ability to poll all the running threads for their currently handled exception would be fantastic.

There is an exposed function named `sys._current_frames()` that allows to list the current frame handled by CPython. Having an equivalent for `sys._current_exceptions()` that would return the content of `sys.exc_info()` for each running thread would solve the issue.
