> With Flip-6, we changed the default behaviour how slots are assigned to
> {{TaskManages}}. Instead of evenly spreading it out over all registered
> {{TaskManagers}}, we randomly pick slots from {{TaskManagers}} with a
> tendency to first fill up a TM before using another one. This is a regression
> wrt the pre Flip-6 code.
> I suggest to change the behaviour so that we try to evenly distribute slots
> across all available {{TaskManagers}} by considering how many of their slots
> are already allocated.
