Well, if you just want to keep track of your current directory in your title bar, there's no need to patch zsh...For a start it's a little more efficient to only change your xterm title when you need to - ie. when you change directory - this can be done with the "chpwd" function, like so :

chpwd () {
        local dir=`print -D ${PWD}`
        local title=${LOGNAME}@$(uname -n):$dir
        print -n -D -P "\033]2;${title}\007"
}

Enjoy,
 Andrew.
