you can't be in a post and a start at the same time, and that is clearly legal to do * Fix interptretation of when the epochs start for MPI_Fence. Only start an epoch if communication actually occurs, otherwise it isn't actually an epoch. I don't know who thought that wording in the MPI standard was a good idea, but can't change it now... This commit was SVN r9139.
