This example does not much: It just spans over-polite actor that yield a large amount
of time before ending.
This serves as an example for the simgrid.yield() function, with which an actor can request
to be rescheduled after the other actor that are ready at the current timestamp.
It can also be used to benchmark our context-switching mechanism.
