The sequence

 >             ctx.setCachingEnabled(true);
would not cleanup ALL caches, it was only addressed in Rhino CVS tip, 
see http://bugzilla.mozilla.org/show_bug.cgi?id=213279 which removed all 
static caches from Rhino and instead stores then in the top level scope 
object.

Note that Context does not store any objects or caches, it the scope 
object that does and you should ALWAYS use the following try/finally 
pattern when using Context.enter/exit:

Context cx = Context.enter();
try {
     use cx
} finally {
     Context.exit();
}
