-/**
- * This class provides support for implementing Java-style synchronized
- * methods in Javascript.
- *
- * Synchronized functions are created from ordinary Javascript
- * functions by the <code>Synchronizer</code> constructor, e.g.
- * <code>new Packages.org.mozilla.javascript.Synchronizer(fun)</code>.
- * The resulting object is a function that establishes an exclusive
- * lock on the <code>this</code> object of its invocation.
- *
- * The Rhino shell provides a short-cut for the creation of
- * synchronized methods: <code>sync(fun)</code> has the same effect as
- * calling the above constructor.
