It will operate, but changes to all but the last Emacs instance to
save the customizations will be lost.

You will get a warning if customize *does not* kill the .emacs buffer
after saving customization, which is currently the case, but that is
precisely what the original poster wanted to change.

Also, you will not get a warning if the user manually kills the .emacs
buffer.
