[Cython] OpenMP problem

[Dag Sverre Seljebotn]

That sounds risky; I think we should consider master as non-rebaseable except in emergencies. So fixes should be pushed to release and then merged into master. Of course, for something like this with no development depending on it one can just delay the merge for a day or two in case more fixes show up.
