+ * This is now version 3 of the XLine subsystem, let's see if we can get it as nice and
* efficient as we can this time so we can close this file and never ever touch it again ..
*
* Background:
* than it could have been, something which we address here.
*
* VERSION 3:
- * All lines are (as in v1) stored together -- no seperation of perm and non-perm. Expiry will
- * still use a sorted list, and we'll just ignore anything permanent.
+ * All lines are (as in v1) stored together -- no seperation of perm and non-perm. They are stored in
+ * a map of maps (first map is line type, second map is for quick lookup on add/delete/etc).
*
- * Application will be by a list of lines 'pending' application, meaning only the newly added lines
- * will be gone over. Much faster.
+ * Expiry is *no longer* performed on a timer, and no longer uses a sorted list of any variety. This
+ * is now done by only checking for expiry when a line is accessed, meaning that expiry is no longer
+ * a resource intensive problem.
*
- * More of course is to come.
+ * Application no longer tries to apply every single line on every single user - instead, now only lines
+ * added since the previous application are applied. This keeps S2S ADDLINE during burst nice and fast,
+ * while at the same time not slowing things the fuck down when we try adding a ban with lots of preexisting
+ * bans. :)

-/* 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.
