-* bgp_community.[ch]: (community_lookup) New helper function to look
-  up a community list in the hash table.
-
-* bgp_routemap.c: A new community structure was being allocated for
-  every BGP update which matched a route map which set a community.
-  This behavior led to rapid growth in the memory consumed by bgpd.
-  Adding the communities to the hash table addresses the memory
-  growth, but may introduce a problem in modifying or deleting the
-  'set community' statement in the route map.

-* bgp_routemap.c: (route_set_community_delete) When deleting a
-  community in a route-map the old community was being orphaned.  Like
-  the description of the same code in route_set_community, this is a
-  hack, not a true fix.
