Uh, are you sure the results aren't swapped? string_wrapper takes a
parameter called use_strcoll, and it indeed uses strcoll() if that
parameter is true, and strxfm() otherwise. But then it passes *false*
to determine the speed of strcoll(), and *true* to determine the speed
of strxfm()...

Also, place_random_string() needs to insert a terminating zero byte,
otherwise set_test segfaults, at least on my OSX machine.
