set up a randomly-named “spill directory.”
Using a directory name instead of a prefix is a good notion.
mkdir returns false if the directory already exists and is atomic. Problem is, how do you distinguish between failure to create because it exists, and failure to create for some other reason? Eg. permissions.
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

In the absence of evidence, opinion is indistinguishable from prejudice.
