Your .profile is SOURCED, so you putting 'exit 0' causes the non- 
interactive shell to exit.  Change this to use the form:

# set umask
# set path
# if interactive
   # interactive setio
# fi

If you exit, you exit.  launchd doesn't see X11 start (because you  
exited), so it tries again (and you exit again).

"falling off the end of the profile" is not the same as exit $?
