What is the status here?

I kept thinking "Didn't I do this at some point??" and yes, I did: https://github.com/Parallel-in-Time/pySDC/blob/a5498546005050b284b77a4f6bac5b1396f4e181/pySDC/projects/parallelSDC/BaseTransfer_MPI.py#L20

As you know, I'm a very good programmer, so, sure, it works 😉 ... that said, can you please remove my code and replace it with yours, making it indeed...

Relax. "might" means that these things are also called during MLSDC sweeps, but there the `u0` is not changed. PFASST however changes the `u0` during its iterations and that's why...

Hm. Maybe so. In any case, it is currently not there. Tbh, this is all a bit blurry in my head, long time ago. I would assume the base transfer...

Well, tests pass, must be correct, no? 😉

Sorry, this happens with Sphinx 1.6.3, but all is good with Sphinx 1.7.x. Anyway, I was expecting that the error with Sphinx 1.6.3 gets caught by the try-except-block, but it...

Yeah, you are right. I'll go ahead and use Python 3.7. Thanks!

Huh, interesting.. you're right, the transfer operations are not as generic as I thought. For `mesh_to_mesh` I understand this, but are your sure about `mesh_to_mesh_fft`?
