A `Node` (e.g. a `Client`, `Server` or `TailDrop` router) can be in 3 states:
``` rust
enum NodeState {
/// The node just produced a datagram. It should be activated again as soon as possible.
Active,
/// The node is waiting.
Waiting(Instant),
/// The node became idle.
Idle,
}
```
`NodeHolder::ready()` determines whether a `Node` is ready to be processed
again. When `NodeState::Waiting`, it should only be ready when `t <= now`, i.e.
the waiting time has passed, not `t >= now`.
``` rust
impl NodeHolder {
fn ready(&self, now: Instant) -> bool {
match self.state {
Active => true,
Waiting(t) => t <= now, // not >=
Idle => false,
}
}
}
```
The previous behavior lead to wastefull non-ready `Node`s being processed and
thus a large test runtime when e.g. simulating a gbit
connection (https://github.com/mozilla/neqo/pull/2203).
