38* SUMMARY: Testing script with at least 64K of different string literals
39* See http://bugzilla.mozilla.org/show_bug.cgi?id=159334
40*
41* Testing that script engine can handle scripts with at least 128K of different
42* string literals. The following will evaluate, via eval(), a script like this:
43*
44*     f('0')
45*     f('1')
46*     ...
47*     f('N - 1')
48*
49* where N is 0x20000
