r13115 profile of a directory authority

[Peter Palfrader]

12 hours of running r13115 on tor26,

It never got up to the usual traffic because oprofile just seems to bog
down the system, so it pushed about 8Mbps instead of 15.  It read about
the same as usually, so it appears to only have affected directory
traffic, not OR traffic.
