In OS 9, Icons take up so little memory that this is moot point if you 
have more than ~24MB RAM. Not only that, but ALL icons are constantly 
loaded in memory, even if they aren't currently being displayed. Rather, 
all icons that existed at the time of your last desktop database rebuild 
are always in memory; most of the balance are, too.

I haven't started porting any of my Applications to OS X yet, so I don't 
know if this holds true in OS X or not.
