From Mark Allen: "On windows when multiple hosts were used, it ended up that in ad_ntfs_open.c rank 0 used CreateFile() with OPEN_ALWAYS and everybody else used OPEN_EXISTING, and those ranks all saw ERROR_FILE_NOT_FOUND. As a fix I added a retry loop and eventually (within 4-5 sec) the remote ranks would see the file." Simply have all processes create the file, as was done long long ago.
