Prior to this CL, (*Server).run only filters out inactive connections
when it accepts a new connection. If existing connections complete,
their associated resources can't be garbage-collected until either the
next connection is accepted or the Listener is closed.
This change moves the open-connection accounting to an explicit hook
passed to newConnection, eliminating the need to call Wait entirely.
