Swift Concurrency: Feedback Wanted!

However I got a crash with Task.sleep(1000) (if I change time from 1000 to 100 than everything is fine).

Thanks, we're aware of this crash -- we'll look into it!

Sorry for the trouble, but for now in Beta 1 please avoid using the asynchronous Task.sleep

There's a workaround for the short term: set SWIFT_DEBUG_CONCURRENCY_ENABLE_COOPERATIVE_QUEUES=NO in the environment when launching your process.
