I'm afraid I no longer have all the details of this design in my head, and I have no idea what the fix does (and no time to read up on everything). The OP says "If you do not await gather" -- what happens if you do await it? Do the tasks then get killed? It seems strange to both cancel the task and set its exception. The docstring for gather() seems to be pretty clear that cancellation and failure of one task should not affect other tasks. So this argues against the PR.
