ListStreamOps

Nondeterministically merges a (static) list of streams in to a single output stream.

When any of the merged streams fail, then the output stream and all other inner streams are interrupted, resulting in a stream that fails with the error of the stream that caused initial failure.

Finalizers on each stream are run at the end of the stream, concurrently with other stream computations.

Finalizers on the output stream are run after the output stream has finished (i.e., all open inner streams have finished).

See NestedStreamOps.parJoinUnbounded for a strictly more powerful (albeit slower) variant capable of merging a stream of streams.
