## Message

```
std.Io.Threaded: fix group closure leak

More tasks could be added to the group at any time before it completes,
so it's not valid to look at the `token` passed in here.

There's also a related bug in `Threaded`, which is that tasks spawned in
a group after it is canceled will not observe that cancelation, but that
is a more complex bug which needs some deeper design changes.
