* This class is the ancestor of every activities that an actor can undertake.
* That is, activities are all the things that do take time to the actor in the simulated world.
- *
- * They are somewhat linked but not identical to simgrid::kernel::resource::Action,
- * that are stuff occurring on a resource:
- *
- * - A sequential execution activity encompasses 2 actions: one for the exec itself,
- * and a time-limited sleep used as timeout detector.
- * - A point-to-point communication activity encompasses 3 actions: one for the comm itself
- * (which spans on all links of the path), and one infinite sleep used as failure detector
- * on both sender and receiver hosts.
- * - Synchronization activities may possibly be connected to no action.
