* {@link java.lang.Error} sublcass that indicates a lua thread that is no
* longer referenced has been detected.
*
* The java thread in which this is thrown should correspond to a
* {@link LuaThread} being used as a coroutine that could not possibly be
* resumed again because there are no more references to the LuaThread with
* which it is associated. Rather than locking up resources forever, this error
* is thrown, and should fall through all the way to the thread's {@link Thread#run()} method.
*
* Java code mixed with the luaj vm should not catch this error because it may
* occur when the coroutine is not running, so any processing done during error
* handling could break the thread-safety of the application because other lua
* processing could be going on in a different thread.
