Great work! Thank you very much!
My application does not crash any more. Well, at least it didn't
crash at the `usual' point, and it's still running now, and up to now
the results are more or less equal to those with non-ghosted vectors.
If this remains to be true until the application finishes, I think
that we can consider the ghosted vectors as finished and enable them
on default; wouldn't you agree?
Of course, my residuals are again slightly off (fifth version now).
I think I should try out what happens when I switch back to
non-ghosted vectors now. I will do that as soon as the current run
has finished (which will not be before tomorrow).

Oh, I should have known this since I ran into that pitfall at least
once before. I somehow find the required parameter order
counterintuitive, but I can't state any reason why.

Well, it's actually one of the best ways to come back, which does,
however, not mean that it's a good way. I mean, "come back from a
vacation" and "good way" kind of contradict each other, don't they?
Best Regards,
Tim
