In the info thread, it is mentioned that threads will be handled differently with this API. (in order to allow the servers to be multi-threaded.) Does each plugin end up in its own thread, or will it be necessary to worry about syncing between different hook calls? For example, if the the server is handling two players in different threads, how will the onBlockCreate (or whatever) events be handled. Will each thread call the plugin hooks, and so the plugin will have to sync between hook calls?
