[tor-talk] Two tor clients

[cats]

I have been experimenting with the thought of running two Tor clients at
once on my machine. So I decided to try it and modified the source a bit
to let me run two clients at once (of course with separate data dirs).
But they both get the same exit node, and if I try to switch exit node
on one of them via its control port, they both get switched. 

I'm a bit curious about this behavior. 
Anyone know why it's behaving like that?
