Of course, having (long, TimeUnit) argument pairs is a performance
hack, but there's not much demand for an improved API, and I still
hope that someday we'll have proper value types in Java, at which time
adding support for value type durations will be more attractive.  So
let's do nothing else for now, unless there's a more urgent compelling
reason?
