How can I reconnect to a remoteapp session?

This happened to me when we had a batch file launching the application, or a helper app that launched an app but then closed. in these cases, remote app has no way to know if the app is still running because the process it originally launched (which then launched another process) had closed. And since a single remoteapp session can have multiple apps running in it, it's not safe for remote app to assume that joining a disconnected session means that the requested app should not launched because it might be a different app that started the session.
