Agreed. There should absolutely be an option to retain the unsafe behavior,
since at the very least it can be useful to have Emacs stick around while
exploring the behavior of a bug in situ. So we won't delete the longjmp code,
we just might change the default behavior to something more consistent with
safer practices.

Also completely agree on the in-the-field experience part. I'm not even sure
we'll change the default behavior right away; we might give it a few releases
to see how it goes, and to hear back from people who've decided to turn it on.
