It's in use by extensions, that are now broken. The next victim will be
the http interface, since httpd callbacks have the same problem.

These are important features. I think the issue could be fixed by
protecting the lua state with a mutex. For a callback to run, the main
thread would have to either have exited, or be sleeping or polling or
inside another such function; and two different callbacks would be
mutually exclusive.
