:) Glad to hear I am not the only one facing this. However, looking at
the standard - it looks like it may be "a bug". Not the easiest to read,
but my understanding of this leans to calling opening a file using
"/some/path/to/file/" is wrong:

[ENOTDIR]
    A component of the path prefix names an existing file that is
    neither a directory nor a symbolic link to a directory; or O_CREAT
    and O_EXCL are not specified, the /path/ argument contains at least
    one non- <slash> character and ends with one or more trailing
    <slash> characters, and the last pathname component names an
    existing file that is neither a directory nor a symbolic link to a
    directory; or O_DIRECTORY was specified and the /path/ argument
    resolves to a non-directory file.
