In #9986, Kyri noticed that `Clock.sleep(Duration.Infinity)` won't be scheduled. This is also true if the Duration is instantiated with `fromNanos` - meaning that `ZIO.infinity` has been (and still is) semantically equivalent to `ZIO.never`.
```
import zio.Duration
Duration.fromNanos(Long.MaxValue) match {
  case Duration.Infinity => "INF"
  case _                 => "NOT"
}
```
