parallel.waitForAll
Switches between execution of the functions, until all of them are finished. If any of the functions errors, the message is propagated upwards from the parallel.waitForAll call.[1]

The file download and read for the file name will execute in parallel, taking turns until both return. Since both read and http.get yield regularly (the first one waiting for characters, and the second waiting for a response), no deadlocking occurs. | |||
