Description
They changed these VMs recently. I wonder if the new ones are lower performing?

Research direction
Start with the AsyncSuite test fromFutureCancelable should backpressure on cancelation and reproduce the 20-second timeout on macos-14. Compare its behavior with other VM environments and inspect the cancellation timing involved. Done means determining whether the failure is environment-specific and establishing a reliable passing test outcome.
