66 Press Enter to create three threads and start them.
67 The threads wait on AutoResetEvent #1, which was created

69 This puts AutoResetEvent #1 into the unsignaled state.

71 Thread_1 waits on AutoResetEvent #1.
72 Thread_1 is released from AutoResetEvent #1.
73 Thread_1 waits on AutoResetEvent #2.
