Research direction
Start with cats.effect.std.SupervisorSuite.async, specifically the “restart / cancel race” test, and inspect the linked Windows CI log for the timeout. Trace the test and the reported stack frames in Runners.scala, WorkStealingThreadPool.scala, and WorkerThread.scala; done means the test no longer times out on the reported environment.
