[tor-dev] Log output cause for concern?

[Steve Snyder]

Over 3 days I've gotten 9 instances of the sequence shown below.

This on Tor v0.2.5.8-rc / x86_64.  I am at 80% CPU utilization with
BandwidthRate set to 90Mbps on this 100Mbps interface.

Should I be concerned about this log output, or is it just verbose
because v0.2.5.x is still in development?
