This already fixes a lot of possible problems that can happen when a script is running and modifying some part of a sprite that is being backed up in a background thread. We still need some work to being able to lock a sprite two or more times in the same thread to write it. E.g. an app.transaction() should lock the sprite for write access, but the script transaction function could call a command, and that command could use a ContextWriter to lock the sprite again. At the moment this is not possible because we need a re-entrant RWLock implementation.
