Maybe there is another reasonably simple solution to the "optimal" task:cpu allocation problem. Add priorities reflecting: - required printing order (minor issue - printing not much work) - time needed per task (loads of computation) We could estimate the latter, more or less I think, by separating out single tasks that have been assigned a particular piece of work and then measure how long they run on average.
