Tor seems to build+timeout circuits for hours when offline/idle

Since I've upgraded to .7-alpha I am having my log file filled with the above message, which is generated a couple of times a second!
I have, so far, accumulated over 14,000 lines with this crap, which seems to be generated when tor was left idle (unused) overnight. I had to increase my log level (to "warn") in order to get rid of it temporarily, but that isn't good enough, since I cannot see my other (very useful) messages appearing at that level (notice) without having my log filled rapidly.

Here's the logline from the original bug title: "No circuits are opened. Relaxed timeout for a circuit with channel state open to 60000ms. However, it appears the circuit has timed out anyway. 0 guards are live."
