Start with DispatchStreamProcessorTest.raceToStream() and the stack trace through CompletionStageDisposable and StreamableForEach.forEach(). Reproduce the failure and trace why CompletionStageDisposable is neither awaited nor explicitly ignored during this path. Done when the test passes without undeliverable exceptions or the allocation trace overflowing the stack.
