+ * See http://bugzilla.mozilla.org/show_bug.cgi?id=159334
+ *
+ * Testing that script engine can handle scripts with at least 64K of different
+ * string literals. The following will evaluate, via eval(), a script like this:
+ *
+ *     f('0')
+ *     f('1')
+ *     ...
+ *     f('N - 1')
+ *
+ * where N is 0xFFFE
