[Junchao Zhang]

We met SF + Windows errors before.  Stefano wrote the code, which I don't
think was worth doing. SF with MPI one-sided is hard to be correct (due to
shared memory programming), bad in performance, and no users use that.
I would suggest we just disable the test and feature?   Stefano, what do
you think?
