libdispatch efficiency tips

I suspect most developers are using the libdispatch inefficiently due to the way it was presented to us at the time it was introduced and for many years after that, and due to the confusing documentation and API. I realized this after reading the 'concurrency' discussion on the swift-evolution mailing-list, in particular the messages from Pierre Habouzit (who is the libdispatch maintainer at Apple) are quite enlightening (and you can also find many tweets from him on the subject).

    if ([text isKindOfClass:[NSString class]] && !text.length) {
        // no text means no height
        return 0;
    }
    
    NSStringDrawingOptions options = NSStringDrawingUsesLineFragmentOrigin | NSStringDrawingUsesFontLeading;
    CGSize size = [text boundingRectWithSize:CGSizeMake(maxWidth, CGFLOAT_MAX) options:options context:nil].size;
