The oldest sessions seem to be only 24h old if I'm reading the changed
field correctly.  I checked the logs, and we only have about 1000 unique
users logging into IMP per day, with maybe double that number of actual
logins per day.  This confuses me since it seems odd that we'd have more
active sessions <=24h old than successful logins per day.  I must be
missing something.
