@achristianson statefulness helps use RAII to eliminate temp files, whereas
other techniques don't do this. It's a balance between cleaning them up
automatically or requiring the user to. As I saw previously with the code I
removed, this was not done, and I fear most users won't properly do this. I'm
with you. My initial implementation was just a simple create file without
tracking. I'm still on the fence about that. We should require users to remove
files, but that's not an expectation from creating temp files.
