Actually, I don't believe that's true. It imposes an extra function call for
each two items that are compared. Depending upon the sort algorithm that's
implemented in the native Array.sort() and how out-of-order the items are to
begin with, this means a likely minimum number of extra function calls is
the number of rows in the table, and the actual number could be much, much
greater.
