How can I set going more one Tor daemons?

[Ringo]

"Cover traffic is only there if the tor instance(s) also run as relay."

I was talking about clients, not servers just to clarify. If multiple
Tor instances are running in client mode (or even in one instance, if
there's a lot of traffic), it becomes harder to do traffic analysis and
pin one circuit to one user.

Am I mistaken in that conclusion?
