If my theory is right, this would actually be counterproductive. The
leak I think I'm seeing is associated with backend exit and so the way
to slow it as much as possible is to prolong backend lifetime as much
as possible. Joe, what is the mean lifetime of your connections anyway?
I assume they don't stay up forever.
