The persistent connections are working properly. The idle connections
are expected given that the Apache child process are not closing them
(A la non-persistent). The connections do go away after 1000 requests
(MaxChildRequest).
I decided to move towards persistent connections since prior to
persistent connections the idle vs startup were reversed.
