+* SUMMARY: Testing script with at least 64K of different string literals
+* See http://bugzilla.mozilla.org/show_bug.cgi?id=159334
+*
+* Testing that script engine can handle scripts with at least 128K of different
+* string literals. The following will evaluate, via eval(), a script like this:
+*
+*     f('0')
+*     f('1')
+*     ...
+*     f('N - 1')
+*
+* where N is 0x20000
