Here's a snippet from my zshrc which does it, not sure if it's perfect
though.

DIRSTACKSIZE=32
DIRSTACKFILE="${HOME}"/.zdirs

autoload -U is-at-least
# Keep dirstack across logouts
if [[ -f ${DIRSTACKFILE} ]] && [[ ${#dirstack[*]} -eq 0 ]] ; then
    dirstack=( ${(f)"$(< $DIRSTACKFILE)"} )
    dirstack=( ${(u)dirstack} )
fi

# Make sure there are no duplicates
typeset -U dirstack

# Share dirstack between multiple zsh instances
function chpwd() {
    if is-at-least 4.1; then # dirs -p needs 4.1
        # Get the dirstack from the file and add it to the current dirstack
        dirstack+=( ${(f)"$(< $DIRSTACKFILE)"} )
        dirstack=( ${(u)dirstack} )
        dirs -pl |sort -u >! ${DIRSTACKFILE}
    fi
}
