Load time is usually considered wastable since it's a one-time penalty, 
although an indexing (as opposed to hashing) lookup would most likely 
have some serious impact on that as well, since the hashbuckets don't 
have to be populated (comparable to roughly a 1/5 of the time it would 
take to generate md5 checksums of all the hashed entries).

What's really remarkable is that this will only be a memory/speed 
exchange for extremely large configurations, where the added object 
variables and object index tables require more memory than the 
statically sized hashbuckets.
