boinc

    - a project overestimates job FLOP counts
    - the client starts jobs in EDF mode
    - as job progresses and fraction done increases,
        its completion time estimate decreases until
        it's no longer a deadline miss.
    - job gets preempted by other job from that project;
        you end up with lots of partly completed jobs.
    Solution (I hope): if an app version has running jobs,
        compute a "temp DCF" for the app version,
        which is the min of dynamic/static estimates for its jobs.
        Apply this scaling factor to completion time estimates
        for unstarted jobs in RR simulation
- client: the estimation of remaining time of running jobs was wrong
    (how did this bug survive so long?)
