commit 99ecd73f801af841dbd4d36bf0054129c5cbeff7
Author: Rob Latham <robl at mcs.anl.gov>
Date:   Tue Apr 15 11:06:55 2014 -0500

    Disable "create on one, open on all" for NTFS
    Some NTFS deployments don't like the optimization where one process
    creates a file and all processes open.  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.
