Yes, that's what I was thinking of. But I'd have called it hash. 

I already changed this in my local copy, but it didn't improove too much. If 
you want I can check these changes into SVN. But I don't know if it's the 
right way.
If you want I can search more from this point. 
Maybe it's worth trying to removing all items from memory as soon as they are 
no longer needed. 
I'm thinking if it would make sense to read all data from the planet script 
into a loacl database and then work with the data from there.
