Comment:
Reopening as the reporter still sees this in 8.2.1.
> How did you launch the two processes? On a Unix like terminal emulator?
(I've tried on MINGW64, but there it is even worse since I don't see any
output). In my case I was using Windows Power Shell, but I get the same
result in the old Windows Command Prompt.
Yes, in a mingw64 msys2 environment under `bash`.
> And regarding the tests, isn't it possible to include the example you
posted above as an integration test for the `Control.Concurrent` library?
We could propose that it be added to `async`, but that won't help catch if
GHC regresses.
