Well, we do use openblas+openmp for years. I was always compiling openblas (with, namely, USE_OPENMP = 1), that is why I never noticed the problem we see now. When running yade, PFV uses openblas while python libs use atlas (see [1] #4), so the bug you mention is not affecting us.

It should fix completely.
Could we have alternatives in the dependencies? I think I've seen that in deb packages sometimes. E.g. installing yade would need to have at least one of blas/atlas/openblas, but you have a choice (maybe even cublas for gpu?). It would apply for 12.04 and Jessie as well. It is not bad for benchmarking the libs.
