When does OS X decide to give your app a spinning beach ball? What can you do when programming an application to avoid this?
The window server will show the spinning wait cursor when the frontmost application, or the application that has a window under the mouse pointer, has not responded to events from the window server within a certain window of time.
To avoid the spinning wait cursor, an application needs to service events in a timely fashion. There’s no way around this window server behavior, and for good reason: Applications on Mac OS X aren’t ever supposed to be unresponsive to the user.
