I think Justin has answered your question. The documentation states that a fresh new process will be created only when it's needed.
So it all points out to System.exit() probably not terminating your process. It just calls Runtime.exit(), which states in its doc: "This method is unlikely to be useful to an Android application." Try calling Process.destroy() if you haven't already, or some other way to kill your process (see ActivityManager), and make sure you have the needed permissions. Remember: that kind of thing should *never* be done by regular apps, only by those aimed at testing/measuring/debugging. If this is not the case, most likely you shouldn't be doing that. Normal apps should let the platform handle the resources by itself.
