Deflakes the test by ensuring that results come in out of order for the `imap_unordered` tests instead of relying on random `time.sleep`s. In the process of rewriting the tests, I discovered a bug in the implementation. We weren't re-fetching available object refs from the queue once we had gotten at least one, which caused the tests to hang. Added a timeout to the `ray.wait` call so we continually check for new object refs to add to the batch. --------- Signed-off-by: Edward Oakes <ed.nmi.oakes@gmail.com> Signed-off-by: elliot-barn <elliot.barnwell@anyscale.com>
