A thread is just like any other value in Lua when it comes to garbage
collection.  If the thread becomes unreachable from the roots - that is
not stored in a global variable, on the stack, or reachable via a chain
of references from any of those - then the next time the garbage
collector runs it will reclaim the thread.
