Replying to [comment:1 duncan]:
> It could be atomic but the error code / exception could not necessarily
be accurate. It could check afterwards if the path that already existed
was a file or directory, but of course that will not be atomic.
Hmm, ok, maybe I don't want atomicity but the illusion of it :-)
Actually, I'm not sure if this is the right thing for me to want, but I
might like some sort of check afterwards (so createDirectoryIfMissing
should catch its createDirectory exception, and if the path really is a
directory, ignore the exception)... basically whatever it takes to let me
continue using this function in my blissful ignorance.
