This is impossible. If you don't touch the file system you have no
way to know if the path is unique.
I think Ben wants to avoid filesystem modification (let us ignore atime
here). So one can read the filesystem to see what is current, but he
does not want to actually make any new filesystem entry.
Hmm -- well, he says "the goal entails having no filesystem activity for
this", and seeing what already exists definitely requires file system
activity . . .
