   I realized it when I was half done implemented but was too lazy to do it correctly. 

   Also PetscSynchronizedFlush() should be changed to use the PetscViewerFlowControlStart() paradigm allowing bigger chunks then one message at a time for flow control, see for example VecView_MPI_Binary() again I was too lazy to do that correctly.

   So someone can do these things or add them to http://www.mcs.anl.gov/petsc/petsc-as/developers/projects.html
