| 73 | * the specified number of milliseconds. In other words, yield just says, |
| 74 | * end my timeslice prematurely, look around for other threads to run. If there |
| 75 | * is nothing better than me, continue. Sleep says I don't want to run for x |
| 76 | * milliseconds. Even if no other thread wants to run, don't make me run. |
