Make sure conn object always gets cleaned up by using a `boost::shared_ptr`. This makes valgrind happy - before this commit, one connection object always leaked at shutdown, as well as can avoid other leaks, when for example an exception happens. Also add an explicit Close() to the !ClientAllowed path to make it similar to the normal path (I'm not sure whether it is needed, but it can't hurt).
