Note that this affects both debathena-finger and stock finger (since we run finger.debathena-orig for network finger, for some reason I don't quite understand).

I've seen this on a couple of other machines like ozok.

Is this still true with all the finger changes?

If so, this sounds like an upstream bug.

keithw points out that who attempts to filter out stale utmp entries, and finger does not, so possibly this logic should be ported from upstream who to upstream finger.
