Hi, I found that if to call run_until_complete() in the task while the event loop will be running, a coroutine sent to run_until_complete() will be performed despite the exception raised from run_until_complete(). It seems to me, it would be better to cancel such a coroutine or just do nothing with it.

Agree, this is a bug.

This commit seems to generate some warnings in the nested run_until_complete test. The check for running loop is now done at run_until_complete itself before going through the below code in it to create a future and raised a RuntimeError by run_forever as the test used to do. Not sure why CI doesn't have these warnings.

Ooh, you are right. The warning is printed only, test runner thinks that the test is ok. I'll prepare a quick fix.
