BeOS & Derivatives "The primary intention of my previous article was to make it very clear why and when locking is needed in multithreaded applications. In this article, I want to present my experiences in writing a new prototype for a replacement of the document model in WonderBrush and how it is manipulated and rendered asynchronously."

I have not tried Photoshop in a while, but last time I did, I was not so happy with the shape editing for example. The document updated no sooner than when I released the mouse! While manipulating the path, only a preview was shown. When I tried Xara, the graphics would switch from realtime update to preview as soon as things got too slow. I didn't find that ideal either. I have worked with many apps over the years... whenever manipulating something is locked to the rendering speed, things become painful. What's also important is that on multi-core computers, threads are actually running in parallel, and without threads, your app uses much less resources than would be available. I don't see the argument against multi-threading. It's a little more complicated? So what if the result is better.
