watcher ran a thread per watched directory (the texture pack's, the graphics mods') so that a texture file changed on disk while a game ran was loaded again; on Windows its backend throws, so its file was the one built with exceptions. A texture pack or mod is now read as the game starts, and a change to it is seen at the next start. With it go Common::FilesystemWatcher, the library's map from file to asset kept only to answer the watcher, and the asset cache's dirty asset queue that only the watcher filled.
