---------------------------------------
Thanks for the pointer [~xintongsong]. I will take a look how you solved the problem and see
how to backport it.

> 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.
