linux下的结果：
Sat Jan 12 2008 20:55:26.459703
Sat Jan 12 2008 20:55:26.460899 sleep 1 // 1.196ms
Sat Jan 12 2008 20:55:26.466037 sleep 5 // 5.138ms
Sat Jan 12 2008 20:55:26.476203 sleep 10 // 10.166ms
Sat Jan 12 2008 20:55:26.526348 sleep 50 // 50.145ms
Sat Jan 12 2008 20:55:26.626466 sleep 100 // 100.118ms
Sat Jan 12 2008 20:55:27.626739 sleep 1000 // 1000.273ms
windows下的结果：
Sat Jan 12 2008 22:51:07.993000
Sat Jan 12 2008 22:51:08.009000 sleep 1 // 16ms
Sat Jan 12 2008 22:51:08.009000 sleep 5 // 0ms
Sat Jan 12 2008 22:51:08.024000 sleep 10 // 15ms
Sat Jan 12 2008 22:51:08.071000 sleep 50 // 27ms
Sat Jan 12 2008 22:51:08.181000 sleep 100 //110ms
Sat Jan 12 2008 22:51:09.181000 sleep 1000 // 1000ms
由此看来，windows下sleep的精度为15ms，，但是1000ms以下的误差都比较大
