1790 We don't sort when inserting. Also, we sort and eliminate
1791 duplicates if there is an unsorted section. Typically, this will
1792 only happen once, because we do all insertions before lookups. We
1793 then use bsearch to do a lookup. This also allows lookups to be
1794 fast. So we have fast insertion (O(log N) due to duplicate check),
1795 fast lookup (O(log N)) and one sort (O(N log N) expected time).
1796 Previously, all lookups were O(N) because of the use of the linked
1797 list and also all insertions were O(N) because of the check for
1798 duplicates. There are some complications here because the array
1799 size grows occasionally, which may add an O(N) factor, but this
1800 should be rare. Also, we free the excess array allocation, which
1801 requires a copy which is O(N), but this only happens once. */
