I'm not so sure about that. We don't know the internals of the flash player where I'm sure a lot of performance optimizations have occured - perhaps with garbage collection, for example. Throw threading into the mix and I'm sure the speed and stability of the flash player could become compromised. I think there is a lot to be said about the approach that Flash is taking .. I've always strived for single threaded environments even when multi-threaded capability was available. Threading brings up complexities which rarely pay off in the end. However, if they're going to do this, they need to make it easier to use.
