buggy tracker behavior?

Hi,

I'm testing out MogileFS and am getting some results from the tracker that I
didn't expect.  I'm wondering whether it's a bug or a misunderstanding on my
part.  I have a file saved to two devices on two different systems.  I
unplugged one of the systems/devices (dev1 on .22) from the network and
noticed that the tracker will sometimes respond to GET_PATHS with 2 paths,
for some reason:

$ telnet localhost 7001
Trying 127.0.0.1...
Connected to localhost (127.0.0.1).
Escape character is '^]'.
GET_PATHS domain=test&key=thisismykey
OK path2=http://192.168.0.22:7500/dev1/0/000/000/0000000054.fid&path1=http://192.168.0.23:7500/dev2/0/000/000/0000000054.fid&paths=2
GET_PATHS domain=test&key=thisismykey
OK path1= http://192.168.0.23:7500/dev2/0/000/000/0000000054.fid&paths=1
GET_PATHS domain=test&key=thisismykey
OK path2=http://192.168.0.22:7500/dev1/0/000/000/0000000054.fid&path1=http://192.168.0.23:7500/dev2/0/000/000/0000000054.fid&paths=2
GET_PATHS domain=test&key=thisismykey

GET_PATHS domain=test&key=thisismykey
OK path2=http://192.168.0.22:7500/dev1/0/000/000/0000000054.fid&path1=http://192.168.0.23:7500/dev2/0/000/000/0000000054.fid&paths=2


I would have guessed that GET_PATHS would only return the 1 available path,
given that I'm not setting noverify.  Whether or not that's how it's
supposed to work (could someone verify whether my guess is correct,
though?), my knee-jerk reaction to the sporadic behavior is to think there's
something wrong.  Thoughts?

I'm using the latest revision from CVS, btw.

Thanks.
