Ah yes, I saw that earlier, from an earlier version of the code that failed with an exception. But it was enough to raise the warning, which then was suppressed. > Putting an 'await' in front of that call causes the tasks to be run > consecutively, of course.

Doesn't that mean that the await asyncio.gather(...) call is turned blocking? -- Steve “Cheer up,” they said, “things could be worse.” So I cheered up, and sure enough, things got worse. -- https://mail.python.org/mailman/listinfo/python-list
