Yes. I noticed that. :)
I was only testing with the ByteCounter example that comes with tomcat.That
example uses nio, so there's no new thread. As soon as I use...
```
val ac = req.startAsync();
ac.start(() -> {
// <logic in here>
});
```
The runnable does not get the threadlocal, obviously. :)
Thanks for the feedback Chris!

Thiago.
