Follow up to #4179. I introduced a
prefetchcall which is a hack to get the outer stream to terminate and finalize before inner streams do, by buffering streams to a new stream.
parJoinalso shuffles the results of the inner stream back out to the new stream which isn't strictly necessary.
This PR introduces a
forkingcombinator which behaves identically to
parJoinexcept the outer stream can terminate and finalize before the inner stream, and there is no queueing involved.
