 64. A call to exiwhat cut short delays set up by "delay" modifiers in ACLs.
     This has been fixed.
 
+65. Caching of lookup data for "hosts =" ACL conditions, when a named host list
+    was in use, was not putting the data itself into the right store pool;
+    consequently, it could be overwritten for a subsequent message in the same
