How did this change affect the load time for smaller worlds? I don't 
imagine it would cause too big of a hit but I'd like to do some testing 
to be sure. Maybe the buffer size should be a command-line arg of 
lookat...or maybe the default should just be bumped up to a larger 
number...if you've already done some more investigation here let me know 
so I don't duplicate work.
