Drop fragile XDG_RUNTIME_DIR support
An XDG runtime directory cannot be provided reliably by the shell, because it's supposed to have the same lifetime as the user's login session, and the shell doesn't have a reliable way to keep track of that lifetime. There are probably nonportable ways to get a conforming directory, such as making a request to PAM, but PAM is supposed to set XDG_RUNTIME_DIR itself anyway and also doesn't exist on Macs, which I use most of the time. My configuration isn't actually using XDG_RUNTIME_DIR anyway, so I don't want to provide the misleading impression that a runtime directory with proper behaviour conforming to the specification is definitely available.

# For XDG_RUNTIME_DIR, pick a temporary directory - the spec actually

# *requires* that it's destroyed when the user logs out, so that's handled by a

# file in zlogout. The reason for suffixing /xdg-$UID is that TMPDIR does not
|

# necessarily belong to the current user exclusively (although it does under

# MacOS and PAM). This is especially true if $TMPDIR isn't set at all and /tmp
