Great. https://ghc.haskell.org/trac/ghc/ticket/15313#ticket is created.
I don’t know how to force them to be “cpu multirace on windows”. If you could do that sometime it’d be great. No rush. Thank you!

I'm not sure why these commands fail under heavy load though. I'll need to dive into the source of ghc-pkg to figure out what's happening. Notice that all the framework failures are these plugin tests which modify a package database. A wild guess is that ghc-pkg tries to take a lock on all package-databases or something when it's mutating one. But I'm not intimately familiar with the package store and this doesn't explain why it doesn't happen on Linux. for now one solution I can propose is to create a ticket to track these and mark these tests as cpu multirace on Windows, which will force them to run sequentially. I'll try to take a look at ghc-pkg this week and if I don't figure anything out I'll force the tests sequential on the short term.
