More testing of vfs_glusterfs reveals problems with Microsoft and
Adobe software, and their silly locking.  (For example, Microsoft
Excel opening a .xlsx, or Adobe Photoshop opening a .jpg or .psd).
Dozens of other production applications we use are all fine, for what
it's worth (the bigger the vendor, the more likely it seems their
software is broken.  How amusing).

The following config (without vfx_glusterfs) is the only way I can
make these particular applications play ball.  Still playing with
"fake oplocks" as well to see what broader effect that has.

[prodbackup]
        vfs object = streams_xattr
        path = /prodbackup
        Comment = prodbackup
        browseable = yes
        writable = yes
        guest ok = no
        valid users = +prod
        create mask = 0660
        force create mode = 0660
        directory mask = 0770
        force directory mode = 0770
        hide dot files = no
        security mask = 0660
        force security mode = 0660
        directory security mask = 0770
        force directory security mode = 0770
        kernel share modes = no
        kernel oplocks = no
        ea support = yes
        oplocks = yes
        level2 oplocks = yes
