In particular, I think tasty does some tricky concurrency. Have there been changes in that recently, either in GHC itself or in async, that might be responsible?
The logict-sequence test suite consistently freezes up on the last
test when compiled with GHC 9.4.3. logict-sequence and its test suite
don't do anything special with that GHC/base version as far as I can
see, or anything particularly strange in general, so I'm pretty
confident the problem lies elsewhere. My best guesses are hedgehog,
tasty, and tasty-hedgehog. Has anyone else run into weird issues with
any/all of these on GHC 9.4.3?
