title: Keep NSThread alive and run NSRunLoop on it
body: <p>So I'm starting a new NSThread that I want to be able to use later by calling <code>performSelector:onThread:...</code>. From how I understand it calling that methods add that call to the runloop on that thread, so on its next iteration it will pop all these calls and subsequently call them until there is nothing left to call. So I need this kind of functionality, an idle thread ready for work that I just can call upon it. My current code looks like this:</p>
  
  <pre><code>   - (void)doInitialize
     {
         mThread =  [[NSThread alloc] initWithTarget:self selector:@selector(runThread) object:nil];
         [mthread start];
     }
  
     - (void)runThread
     {
         NSAutoReleasePool *pool = [[NSAutoReleasePool alloc] init];
  
         // From what I understand from the Google machine is that this call should start the
         // runloop on this thread, but it DOESN'T. The thread dies and is un-callable
         [[NSRunLoop currentRunLoop] run];
  
         [pool drain];
     }
  
     - (void)scheduleSomethingOnThread
     {
         [self performSelector:@selector(hardWork) onThread:mThread withObject:nil waitUntilDone:NO];
     }
  </code></pre>
  
  <p>But the thread is not kept alive, and the performSelector:onThread does not do anything. How do I go about this the right way?</p>
