@edgargabriel Found another issue; I fixed and re-pushed. @bosilca saw the fix in Slack and approved it there (so even though my push is after his github approval, he still approved 👍). |

We were initializing the mutex in file_open, but that didn't handle MPI_FILE_NULL. So we move it to the constructor, and therefore it's always initialized for all file handles -- even MPI_FILE_NULL. Signed-off-by: George Bosilca <bosilca@icl.utk.edu> Signed-off-by: Jeff Squyres <jeff@squyres.com>

Thanks to mpi4py test suite for finding this one. 👍
