No, we just exclude objects with _v_ attribute from mid-transaction 
deactivation. There arent many objects in that category, but they do need 

But, your proposal means we would improve the situation for transactions that 
read from an undeterminable number of persistent objects. It does not help 
for transactions that touch an undeterminable number of non-persistent 
objects, or transactions that change an undeterminable number of persistent 
objects. Is the gain big enough to justify the effort?
