  42  * SUMMARY: Testing script with at least 64K of different string literals
  43  * See http://bugzilla.mozilla.org/show_bug.cgi?id=159334
  44  *
  45  * Testing that script engine can handle scripts with at least 64K of different
  46  * string literals. The following will evaluate, via eval(), a script like this:
  47  *
  48  *     f('0')
  49  *     f('1')
  50  *     ...
  51  *     f('N - 1')
  52  *
  53  * where N is 0xFFFE
  54  *
