Prevent STM waking up threads blocked on `threadDelay` #143

Closed amesgen closed 8 months ago

Closes #142

nfrisby commented 8 months ago

Some good news: this fixes my direct "repro".

Some bad news: I'm seeing a different test failure now, so I'll try to debug that promptly to see if it's my own mistake that is masking more issues like this one.

This fix works for me! My new GSM tests are passing locally. My PR is unblocked (other than needing a CHaP release, etc---I've merely locally backported Esgen's patch to the last io-sim release and used a source-repository-package in my local cabal.project for now).

I'll cut a new hackage release, once #141 is merged.
