The idea is to avoid building a data structure

to process a variably sized and arbitrary shaped
set of source data

design decision how to invoke a job
...
without any trickery, we'll always get two indirections.
Thus, the decision is to turn the 2nd indirection
into a VTable call; this way, basically the JobClosure
also acts as job functor itself.

Fix: missing sanity check in ScopedCollection

funny enough this possible memory corruption
didn't happen in the unit test, because my
compiler optimised the additional int field
of class SubDummy, making it the same size
of the baseclass. Now matters should be safe.

this draft is based on

- my plannings about segmentation and JobTicket

from plain-C, using the information in the
job descriptor datastructure
