It seems the only reason behind `IntMap ()` was the absense of `Data.IntMap.withoutKeys`, which was only added in `containers-0.5.8`.
At the moment we use `Data.IntMap` which is lazy in values, and we initialise values with thunks `testStatus <$> testActions`. This is outright silly: `testStatus` is just a selector for `TVar` field, forcing it to WHNF can do no harm. We also take an opportunity to replace `IntMap.fromList` with `IntMap.fromDistinctAscList`.

I suggest to hold the changes that need a bump to containers until we drop GHC 8.0.

@andreasabel good catch. I can put CPP of course, but I have no reason to keep compatibility with GHC < 8.6 (where 8.6 is only because of GHCJS). How do you feel about dropping earlier versions? |

Thinking it over, I guess it is fine to go ahead with this PR as-is. |

Generally not a fan of fromDistinctAscList as it is easy to break the precondition, but given that the ascending list is right behind it this LGTM.
