* The code passed as argument is supposed to terminate at the exact same simulated timestamp.
* Do not use it if your code may block waiting for a subsequent event, e.g. if you lock a mutex,
template <class F> typename std::result_of<F()>::type simcall(F&& code, mc::SimcallInspector* t = nullptr)

if (SIMIX_is_maestro())

* This is very similar to simcall() right above, but the calling actor will not get rescheduled until
- * actor->simcall_answer() is called explicitely.

+ * Since the return value does not come from the lambda directly, its type cannot be guessed automatically and must

* This is meant for blocking actions. For example, locking a mutex is a blocking simcall.
* First it's a simcall because that's obviously a modification of the world. Then, that's a blocking simcall because if

* If your code never calls actor->simcall_answer() itself, the actor will never return from its simcall.
