when did the object store get changed so that loose objects aren't 
compressed?

if the problem is that the codepath for fetching does an uncompress 
followed by a compress then it would seem that this is a fairly easy 
problem to fix (how hard would it be to add the headers around the 
compressed object to make it look to the receiver like it's a pack with 
only one thing in it)
