// Note that when you create a CFMachPort object, CF will attach the run loop source for the the |
// Mach Port that handles Port Death notifications (aka the Invalidation Callback) to the current |
// thread's run loop. This is something over which there is no control, so be sure to create the |
// CFMachPort on the thread on which you want to handle Port Death notificaitons on. |
