I removed these invariants in #4625, but they might have helped catch the bug from #4739 (comment).
Also, this check for
finished = ...
wasn't quite right, because the fiber mightyield
, returning a value, and causing these fibers to be pushed away before they were really finished.Finally, I think the
manager
fiber here was not really needed. It was added along the way to supporting the Async gem (and eventually became aSync do ... end
