Program Run Analysis:
1, first system scheduling test1 thread put into operation, print the NO. 0 run of information, and then through the delay function to suspend themselves 100 time slices, the system will test2 thread scheduling operation;
2, test2 thread print the No. 0 run information, and then through the delay function to suspend themselves 50 time slices;
3, the system has no task to run, the system will be idle thread into operation;
4, 50 time slices after the test2 thread is awakened, print the 1th run of information, and then continue through the delay function to suspend themselves 50 time slices;
5, the system has no task to run, the system will be idle thread into operation;
6, 50 time slices time, test1 thread is awakened, print the 1th run information, continue to suspend 100 time slices;
7, the Test2 thread is awakened, print the 2nd run of information, and then continue through the delay function to suspend themselves 50 time slices;
8, the system has no task to run, the system will be idle thread into operation;
9, 50 time slices after the test2 thread is awakened, print the 3rd run of information, and then continue through the delay function to suspend themselves 50 time slices;
10, the loop executes 5-9 process.
