at any given time. This function is equivalent to flatMapMerge(breadth, identity).
Emits when a currently consumed substream has an element available
Reactive Streams semantics
@@@div { .callout }
emits when one of the currently consumed substreams has an element available
backpressures when downstream backpressures or the max number of substreams is reached
completes when upstream completes and all consumed substreams complete
