+<h2>Thread Safety</h2>
+
+Luaj 3.0 can be run in multiple threads, with the following restrictions:
+<ul>
+<li>Each thread created by client code must be given its own, distinct Globals instance
+<li>Each thread must not be allowed to access Globals from other threads
+<li>Shared metatables for Number, String, Thread, Function, Boolean, and and Nil

+For an example of loading allocating per-thread Globals and invoking scripts in

+As an alternative, the JSR-223 scripting interface can be used, and should always provide a separate Globals instance 
+per script engine instance by using a ThreadLocal internally.
