       This meant a connection with many messages would use continually-growing
       memory.
 
+JH/46 Use an exponentially-increasing block size when malloc'ing store.  Do it
+      per-pool so as not to waste too much space.  Previously a constant size
+      was used which resulted in O(n^2) behaviour; now we get O(n log n) making
+      DOS attacks harder.  The cost is wasted memory use in the larger blocks.
