Requesting better "too slow" warning message

Over an 18-hour period Tor v0.2.2.34 logged 5 instances of "Your computer is too slow to handle this many circuit creation requests! Please consider using the MaxAdvertisedBandwidth config option or choosing a more restricted exit policy." with several hundred more messages suppressed.

Since I've never seen these message before and because I've changed nothing in the 10 days since I updated to v0.2.2.34, I feel pretty confident I can blow off these warnings.

The message, though, give no indication of how far I am from being able to handle the number of pending requests. How would I know what value to configure MaxAdvertisedBandwidth with? How much more restrictive does the exit policy need to be? The problem is that I don't know if it was a single connection that couldn't be accomplished or 10,000 connections. If the former it makes sense to tweak my config; if the latter I can safely dismiss the warnings as resulting from some sort of attempted attack.

So... can we get more info in the "too slow" warning messages?

Thanks.
