/* STATUS_LOCK_NOT_GRANTED can be generated under not quite clear
circumstances when trying to open a file on NFS with FILE_SHARE_DELETE
only. This has been observed with SFU 3.5 if the NFS share has been
mounted under a drive letter. It's not generated for all files, but
only for some. If it's generated once for a file, it will be
generated all the time. It looks like wrong file state information
is stored within the NFS client, for no apparent reason, which never
times out. Opening the file with FILE_SHARE_VALID_FLAGS will work,
though, and it is then possible to delete the file quite normally. */
