<P>
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.
