One question about the response methods: If I would be using something like `ctx.result(inputStream)` - would it block the [lightweight] thread until all data is written. Or would the handler return and the data transfer happen in the background?
One use-case I've only see marginally addressed in some frameworks is being able to run code past the point where all data is written - e.g. to record logs and metrics around the outcome of a request - e.g. whether the client hung up or all data was stored in socket buffers. If sending the result "blocks", that kind of code can be added naturally with a try/finally block around it.
As far as I understand the docs, it might not block, but one might be able to install an "After" handler? Or would that also only run before the response is actually sent?
