A better solution -- which I use on all systems, even if they have an
up-to-date zsh installed -- is to make your login shell be /bin/sh,
and have your .profile do the exec zsh.  zsh doesn't read the .profile,
so there's no possibility of a loop.  /bin/sh is also likely to start
up faster than the system's zsh.
