title: android startActivityForResult is killing a thread within the parent activity
body: <p>I have an activity which has a thread and a view in it...they're suspiciously similar to LunarLander. To show an in-game menu, i'm calling the startActivityForResult for a different activity which has a number of buttons on it...this is then returning the button type pressed to the parent activity. This is fine except when I carry on in the parent activity, the original thread I had is now TERMINATED. I guess this is happening because the parent activity has lost focus and so the thread is considered dead, but I want to carry on with the thread.</p>
  
  <p>Is there any way I can keep the thread alive? I've tried setFlags on the intent for the new activity but i've not found anything that maintains it..</p>
