It happened again (this time with version 0.1.0.11):

Jul 01 12:58:11.014 [notice] Your DirPort is reachable from the outside.
Excellent.
Jul 01 13:00:20.064 [notice] Your ORPort is reachable from the outside.
Excellent. Publishing server descriptor.
...
Jul 01 17:59:42.204 [notice] conn_close_if_marked(): Conn (addr
[scrubbed], fd 117, type OR, state 5) is being closed, but there are
still 168960 bytes we can't write. (Marked at main.c:579)
Jul 01 18:22:37.592 [notice] spawn_enough_dnsworkers(): 9 of 12
dnsworkers are idle. Killing one.
Jul 01 18:22:37.592 [notice] spawn_enough_dnsworkers(): 8 of 11
dnsworkers are idle. Killing one.

After this no traffic at all, the tor.pid was still there but no process
running and therefor none killed when restarting.
Now I don't think it's just a coincidence.
