```
    Wait for the one-time occurrence of an event.
    This method blocks for a maximum of timeout milliseconds, waiting for the event identified by eventName to occur. A timeout value of 0 means wait indefinitely.
    
    The return value is the number of occurences of the event in question, or -1 if the call timed out.
    
    Parameters:
    
    eventName - The name of the event to wait for
    
    timeout - The maximum number of milliseconds to wait
