Error: Returning from a request handler without responding or attaching an abort handler is forbidden!

This server is excellent under many circumstances.
But when, as part of the request handling, we need to wait for 'something else' to happen, I see some odd behaviour.

e.g. request arrives and we need to fetch some data before responding:

get('/my-stuff', (res, req) => {
   db.query('select * from some_table', (err, reply) => {
        res.end(reply)
})

or request arrives and we need to call out to an external service in order to satisfy it:

get('/auth/twitter', (res, req) => {
   twitterOauth.getRequestToken( (err, token, tokenSecret, results) => {
        if (err) {
            res.end('oops - we could not fetch a token for you')
        } else {
             res.end('append this token to your url')
       }
    })
})

At this point the server reports: "Error: Returning from a request handler without responding or attaching an abort handler is forbidden!"

That's pretty interesting. Any ideas how to fix? (nb this may well be 'me' being supremely dopey!)

You are returning from a request handler without responding. So did you attach an abort handler like it tells you to?

examples/VideoStreamer.js

examples/AsyncFunction.js That's right?

Good info. Thx.

It's a good idea to document this behavior.
