+/* 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.
