-/* Version two, now with optimized expiry!
- *
- * Because the old way was horrendously slow, the new way of expiring xlines is very
- * very efficient. I have improved the efficiency of the algorithm in two ways:
- *
- * (1) There are now two lists of items for each linetype. One list holds temporary
- *     items, and the other list holds permanent items (ones which will expire).
- *     Items which are on the permanent list are NEVER checked at all by the
- *     expire_lines() function.
- * (2) The temporary xline lists are always kept in strict numerical order, keyed by
- *     current time + duration. This means that the line which is due to expire the
- *     soonest is always pointed at by vector::begin(), so a simple while loop can
- *     very efficiently, very quickly and above all SAFELY pick off the first few
- *     items in the vector which need zapping.
- *

/* Version two, now with optimized expiry!
 *
 * Because the old way was horrendously slow, the new way of expiring xlines is very
 * very efficient. I have improved the efficiency of the algorithm in two ways:
 *
 * (1) There are now two lists of items for each linetype. One list holds temporary
 *     items, and the other list holds permanent items (ones which will expire).
 *     Items which are on the permanent list are NEVER checked at all by the
 *     expire_lines() function.
 * (2) The temporary xline lists are always kept in strict numerical order, keyed by
 *     current time + duration. This means that the line which is due to expire the
 *     soonest is always pointed at by vector::begin(), so a simple while loop can
 *     very efficiently, very quickly and above all SAFELY pick off the first few
 *     items in the vector which need zapping.
