I meanwhile did add dot/svg generation in the devel branch.

Here are a few variations of graphs that helped show the (race) problem
that helped make this fix

(there are tooltips when you hold the mouse over a node or edge)

I'm not yet fully satisfied with how the dot generation and styles are
sprinkled all over the code, so maybe I'll refactor it to have some
intermediate representation (e.g. JSON) that gets consumed by a .dot
generator script.

Irrespective of the code quality, such visualizations make it even more
so I'm considering to just stracebuild many more unreproducible openSUSE
