  58 /* Version two, now with optimized expiry!
  59  *
  60  * Because the old way was horrendously slow, the new way of expiring xlines is very
  61  * very efficient. I have improved the efficiency of the algorithm in two ways:
  62  *
  63  * (1) There are now two lists of items for each linetype. One list holds temporary
  64  *     items, and the other list holds permenant items (ones which will expire).
  65  *     Items which are on the permenant list are NEVER checked at all by the
  66  *     expire_lines() function.
  67  * (2) The temporary xline lists are always kept in strict numerical order, keyed by
  68  *     current time + duration. This means that the line which is due to expire the
  69  *     soonest is always pointed at by vector::begin(), so a simple while loop can
  70  *     very efficiently, very quickly and above all SAFELY pick off the first few
  71  *     items in the vector which need zapping.
