tor traffic ratelimiting

[Matt Ghali]

I was on the phone with my ISP today, and as an aside, the engineer 
mentioned that my 768k upstream was pegged at 105% capacity. I was 
surprised, and a little freaked out, since nothing should be 
generating that much traffic.

I killed tor while we were on the phone, and he confirmed that 
almost all traffic on the link dissapeared. I am quite concerned, 
because I have the following statements in my torrc:

BandwidthRate 64 KB
BandwidthBurst 128 KB

from these settings I expect that tor should never be using the 
majority of my available bandwidth- but it seems it is.

Am I missing something here, or has the ratelimiting code been 
quietly broken?

thanks,
matto
