What is the reason that we want to create unique files here? Is it that we are
trying to be consistent with what we do in
`OnDiskOutputFile::tryToCreateTemporary` (or in general how we write files to
disk)? Would it be a good idea to pull out the common utility part and share
some code? It might not be that straightforward and I don't think this is a
blocker.
