In my case a single user login could use multiple values -- each of the
Emacs instances (and inferior processes thereof) that the user ran
during that login session would be seeing a different XDG_RUNTIME_DIR.

If it's intended to be a replacement for TMPDIR though, perhaps changing
XDG_RUNTIME_DIR is no worse than changing TMPDIR.
