[tor-relays] first impression with 0.3.2.8-rcant a fast exit relay

With 0.3.2.7-rc the command /usr/sbin/iftop -B -i eth0 -P -N -n -m 320M showed every then and when (few times in a hour) for 10-20 sec a traffic value of nearly 0 bytes for the short-term period (the left of the 3 values). Usuaally I do poberve between 6 and 26 MByte/sec. With the Tor version from today now the outage is about 1-2 sec, but does still occur. Not sure, if this is an expected behaviour or a local problem.
