That looks like race to me… if it need to ensure there is a handle, it
needs to reserve / create one right then and there and then use it for
the created file (and clean it up if the file can't get created due to
other errors.
True, that. I was swayed by a "but what are the odds?" argument. I will
cogitate more deeply for a v2 patch; all racy logic must be avoided.
