There are two issues: 1 do you want to do anything while waiting, 2 how quick
do you want to respond to the event. In both cases using an event is better.
You can do something else until the event happens (synchronization issuses not
withstanding). With the sleep for a fixed period your response time will be the
full wait period, worst case and half the period on average whereas an event is
probably faster.
