Yes, we can turn it off.   The code without real use is just a maintenance burden.

  Ok, so it could be a bug in PETSc, but if it appears with particular MPI implementations shouldn't we turn off the support in those cases we know it will fail?

MPI one-sided is tricky and needs careful synchronization (like OpenMP).  An incorrect code could work in one interface but fail in another.

   It sounds reproducible and related to using a particular versions of OpenMPI and even particular interfaces.

Without a standalone & valid mpi example to reproduce the error, we are not assured to say it is an OpenMPI bug.

Okay, we have to send this to OpenMPI. Volunteers?

Maybe we should note this in the FAQ, or installation, so we remember how to fix it if someone else asks?
