@parttimenerd Oh, my previous comment about `synchronized` was incorrect: you still have concurrency between the main thread and `RecordingStream` async processor - sorry for confusion.
I also think you need to call `rs.stop()` (which internally calls `awaitTermination`) before closing the stream. This should fix the race in the David's case.
