Review comment:
nit: in our internal fork, we changed these asserts to if-throws (I forgot
to upstream this change, will do it on master branch shortly). I don't think it
matters that much since they've never fired. Anyway, what do you think about
replacing this assert with:
```
if (!channel.eventLoop().inEventLoop()) {
throw new IllegalStateException(
"processMessage() called from non-EventLoop thread");
}
```
