52This statement can be used to resume execution of a previously suspended
53thread. If applied to a thread that is not running, is running, or
54is waiting for a condition to continue execution, this will have no effect.

58Questa istruzione può essere utilizzata per riprendere l'esecuzione di
59un thread sospeso in precedenza. Se applicato a un thread non in
60esecuzione, in esecuzione o in attesa di una condizione per continuare
61l'esecuzione, questo non comporterà alcun effetto.
