Hi,

And how should this "SHA list" be any different from a single tree object, 
except that you now merge it with the commit object?

Really, go back to the mail Martin mentioned.  Having all objects in one 
list kills performance.

No, it is not fast.  Just loading the complete list into RAM is likely 
much, much slower than a simple diff _right_ _now_.

Hth,
