-/* This example shows how to use simgrid::s4u::this_actor::wait_any() to wait for the first occurring event.
- *
- * As for the other asynchronous examples, the sender initiate all the messages it wants to send and
- * pack the resulting simgrid::s4u::CommPtr objects in a vector. All messages thus occurs concurrently.
- *
- * The sender then loops until there is no ongoing communication. Using wait_any() ensures that the sender
- * will notice events as soon as they occur even if it does not follow the order of the container.
- *
- * Here, finalize messages will terminate earlier because their size is 0, so they travel faster than the
- * other messages of this application.  As expected, the trace shows that the finalize of worker 1 is
- * processed before 'Message 5' that is sent to worker 0.
