+* 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 64K of different
+* string literals. The following will evaluate, via eval(), a script like this:
+*
+*     test_var = Array(N);
+*     test_var[0] = '0';
+*     test_var[1] = '1';
+*     ...
+*     test_var[N - 1] = String(N - 1);
+*
+* where N is about 0xFFFD
