Mosh Cleaner

Mosh cleaner kills stale mosh sessions, according to this algorithm:

For each user:
    If user only has one mosh session:
        continue
    For each mosh session other than the most recent of that user:
        If session is currently connected:
            continue
        If session is older than kill-time:
            kill session

kill-time begins at 24 hours and splits in half each time, until a minimum of 1 hour. This amounts to the following semantics:

• Most recent session: never killed
• Any currently connected session: never killed
• Second most recent session: killed if not used for 24 hours
• Third most recent session: killed if not used for 12 hours
• Forth most recent session: killed if not used for 6 hours
• Fifth most recent session: killed if not used for 3 hours
• Sixth most recent session: killed if not used for 1.5 hours
• Seventh most recent session: killed if not used for 1 hour
• Eighth most recent session: killed if not used for 1 hour
• Ninth most recent session: killed if not used for 1 hour
