+ /** @brief Moves the actor to another host
+ *
+ * If the actor is currently blocked on an execution activity, the activity is also
+ * migrated to the new host. If it's blocked on another kind of activity, an error is
+ * raised as the mandated code is not written yet. Please report that bug if you need it.
+ *
+ * Asynchronous activities started by the actor are not migrated automatically, so you have
+ * to take care of this yourself (only you knows which ones should be migrated).
