* - From host0 to host1: 1 byte is exchanged

+ *

* In a parallel execution, all parts (all executions on each hosts, all communications) progress exactly at the
* blocking functions forbidden in this setting, but also modifications to the global state.

* The parameter of on_exit's callbacks denotes whether or not the actor's execution failed.
- * It will be set to true if the actor was killed or failed because of an exception,
+ * It will be set to true if the actor was killed or failed because of an exception or if the simulation deadlocked,
* while it will remain to false if the actor terminated gracefully.
