biggest gain is the reduction from 470 MB of peak memory to 352 MB. Time 
went down from 2:40 to 2:15 it seems most of the time is spent in 
initializing the objects. Changing more ivars to symbols brought the 
time back up to 2:25 but memory down to 227 MB.  Never thought of 
symbols as memory savers before :-)

Thanks for the tip,
