I'm not sure about the WeakReference as there is a cost associated  
with that too. Iterating all my instances once a week to find the  
delta it probably enough for me as I pretty much never delete  
anything. Or is there something I'm forgetting?

Another good point.

Perhaps I should implement my own String, using the first byte as  
bitset for encoding and what not. I'll report back later with any  
findings.

Thanks for the input,
