Description
Very rarely tests that have blocks with async => 1 hang forever. This happenes to many tests, but very rarely, like 1 in 10,000 so it is VERY hard to preproduce, and is likely a race condition. Mainly seeing this with yath, not sure if it also effects prove, but likely does.

Research direction
Start with Test2::Tools::Spec tests using blocks with async => 1 and reproduce the hang under yath, then check whether prove shows the same behavior. Trace the intermittent async execution until the race condition is isolated; done means the hang is fixed and a regression test covers it.
