Details

An occasional problem with async requests is that the user can close a window that is still waiting for a response, then you end up with weird errors about missing Components etc. We should extend the API to support cancelling async operations. This can be achieved be returning something like an nsICancelable from the appropriate methods. Calling cancel on this object will cancel the request. In the first case this will probably be as simple as still running the operation to completion and then not calling the callback.
