  21  * This is now version 3 of the XLine subsystem, let's see if we can get it as nice and
  22  * efficient as we can this time so we can close this file and never ever touch it again ..
  23  *
  24  * Background:
  25  *  Version 1 stored all line types in one list (one for g, one for z, etc). This was fine,
  26  *  but both version 1 and 2 suck at applying lines efficiently. That is, every time a new line
  27  *  was added, it iterated every existing line for every existing user. Ow. Expiry was also
  28  *  expensive, as the lists were NOT sorted.
  29  *
  30  *  Version 2 moved permanent lines into a seperate list from non-permanent to help optimize
  31  *  matching speed, but matched in the same way.
  32  *  Expiry was also sped up by sorting the list by expiry (meaning just remove the items at the
  33  *  head of the list that are outdated.)
  34  *
  35  * This was fine and good, but it looked less than ideal in code, and matching was still slower
  36  * than it could have been, something which we address here.
  37  *
  38  * VERSION 3:
  39  *  All lines are (as in v1) stored together -- no seperation of perm and non-perm. Expiry will
  40  *  still use a sorted list, and we'll just ignore anything permanent.
  41  *
  42  *  Application will be by a list of lines 'pending' application, meaning only the newly added lines
  43  *  will be gone over. Much faster.
  44  *
  45  * More of course is to come.
  46  */
  47
  48 /* Version two, now with optimized expiry!
  49  *
  50  * Because the old way was horrendously slow, the new way of expiring xlines is very
  51  * very efficient. I have improved the efficiency of the algorithm in two ways:
  52  *
  53  * (1) There are now two lists of items for each linetype. One list holds temporary
  54  *     items, and the other list holds permanent items (ones which will expire).
  55  *     Items which are on the permanent list are NEVER checked at all by the
  56  *     expire_lines() function.
  57  * (2) The temporary xline lists are always kept in strict numerical order, keyed by
  58  *     current time + duration. This means that the line which is due to expire the
  59  *     soonest is always pointed at by vector::begin(), so a simple while loop can
  60  *     very efficiently, very quickly and above all SAFELY pick off the first few
  61  *     items in the vector which need zapping.
