I think we should make a release as soon as we can and then a new
release in about a month. I have some things planned for that release.

My suggestion is that we aim for the correct solution and postpone
that to 0.94. Then it would be enough to make a call to
not_working_in_parallel() in a suitable place (reading MeshFunctions).

We also need to solve (or disable) 3. plotting from C++ in
parallel. What's your opinion on that one?
