Moving TMPDIR into the private runtime root left pytest's default <TMPDIR>/pytest-of-<user>/pytest-<n> beneath it. With xdist's popen-gw<n> the real-tmux witness bound a 110-byte socket path, over Linux's 107-byte sun_path limit, so it failed under every worker count while passing serially. The controller now roots basetemp at the private root's pytest directory; xdist hands workers popen-gw<n> beneath it. An explicit --basetemp wins. A tmux-independent witness binds a socket at the same path budget.
