[tor-relays] Bandwidth Authority PID Feedback Experiment #2 Starting

[cmeclax-sazri]

I've been seeing these messages ("hammer" is routine disk maintenance, which 
makes other things run slowly):

Dec 17 05:09:27 darner Tor[1138]: Your computer is too slow to handle this 
many
circuit creation requests! Please consider using the MaxAdvertisedBandwidth 
conf
ig option or choosing a more restricted exit policy. [159 similar message(s)

I also saw this:

Dec 16 22:11:27 darner Tor[1138]: Tor has not observed any network activity 
for
the past 65 seconds. Disabling circuit build timeout recording.
Dec 16 22:11:42 darner Tor[1138]: Tor now sees network activity. Restoring 
circu
it build timeout recording. Network was down for 80 seconds during 3 circuit 
att
empts.

but checking auth.log on my other box shows that this is when I was either 
sending a huge email or rsyncing some files on an ssh connection from 
overseas.
