I think /tmp/ is mounted per user so we should be good.
I have never seen this. In fact, I'm not familiar with any
mechanisms of "per-user" mounts on POSIX systems.
The general practice of creating files in /tmp/ is to either put
the UID in the filename, or use unique random filenames (e.g. via
mkstemp).
If this is security-sensitive, we should not be dismissive about
any aspects of this.
It would also be nice to have a VERY SIMPLE mechanism to delete
old runs (e.g. a day or more).
FWIW, systemd mounts /tmp as a tmpfs, and OS X seems to delete
files in /tmp older than 3 days.
