It is quite ugly, but that does not differ much from v1. At least with
this versions you don't have to jump around to find the arguments for
the callbacks.

As I've said in v1 review I don't quite see a value in introducing
callbacks just to be able to extract 3 repetitions of a for loop.
Especially since the worker functions take pretty diverse parameters.

What would make sense to extract is the checks that validate that the
returned data is in somewhat sane format in the helper that you've added
in patch 1. (also mentioned in previous review).

NACK to 2 - 5.
