Lets you run multiple functions at the same time, alternating between them until all have finished. Note that it takes function names as parameters (eg "function1", "function2", etc), as opposed to function calls (eg "function1()", "function2()", etc).

parallel.waitForAll(receive, send)  -- Run both functions in parallel and wait until both of them completes.
