It's nothing to do with the return type of methods in your Async
interface. I'm talking about RpcRequestBuilder, not RequestBuilder:
http://google-web-toolkit.googlecode.com/svn/javadoc/2.0/com/google/gwt/user/client/rpc/RpcRequestBuilder.html

(and yes, it allows you to use your subclass of RequestBuilder; but
IMO you'd rather show the popup in RpcRequestBuilder#doFinish (or
maybe even earlier, such as in doCreate()), and wrap the
RequestCallback in doSetCallback; but if you already have a
RequestBuilder-subclass, then just return it from doCreate)
