Hi,

I am really liking the new domains feature. However I have a question: "How
do I leave a domain"

Is my undesrtanding correct?:

    function b(callback) {
      // I am running inside the domain created in a
      fs.readFile('some-file', 'utf-8', function(err, val) {
        // I am running inside the domain created in a
        if (err) return callback(err);
        callback(undefined, val.replace('A','B'));
      });
    }
    function a() {
      var d=domain.create();
      d.run(b.bind(null, callback))
    }
    function callback() {
      // I am running inside the domain created in a
    }

If so, then how do I leave a domain? Simply dispose of it? Then in which
domain am I afterwards? Think nested domains. Am I in the one I was in
before doing *domain.run()* in *a*?

I I'm wrong in my understanding, then how do I ensure that all my async
calls/callbacks remain in the domain I created?

I would really appreciate if someone could explain this, since I am about
to embark on some major efforts that would really benefit from using
domains. Understanding how they work would be sort of fundamental ;)

Don't know if you were at Node Summercamp, but we talked a lot about
domains. It's clear that there's lots of confusion about the semantics.
I've got some of the same questions. I had planned on finally sitting down
to explore them tomorrow. I can tell you that domains *are* nested. When
you start a new domain, it goes on a stack. And when you close it, you are
back in the previous domain.
