Re: NSDocument beginSheet on a new document

I also found an example that suggested the following:

       [[NSRunLoop currentRunLoop] 
performSelector:@selector(editCabrilloHeadersForWindow:)
                                              target:self
                                           argument:[windowController 
window]
                                               order:0
                                               modes:[NSArray 
arrayWithObject:NSDefaultRunLoopMode]];

Is it recommend that I go through the runloop or should I just 
performSelector on itself with a delay of 0?
