bug#33629: 27.0.50; Emacs built --without-threads signals (void-function thread-name) when `save-buffers-kill-terminal'

["İ. Göktuğ Kayaalp" <self@gkayaalp.com>]

Reproduce w/ emacs -Q

M-x shell
M-x toggle-debug-on-error (optionally)
C-x C-c

The stack trace:

Debugger entered--Lisp error: (void-function thread-name)
  (thread-name #<thread 0xc453a0>)
  (list-processes--refresh)
  (list-processes t)
  (save-buffers-kill-emacs nil)
  (save-buffers-kill-terminal nil)
  (funcall-interactively save-buffers-kill-terminal nil)
  (call-interactively save-buffers-kill-terminal nil nil)
  (command-execute save-buffers-kill-terminal)

When I look at `(process-list)' at this moment, it's contents is only

(#<process shell>)

I’ve had this with an earlier build (should be from a couple weeks ago),
I don’t have it around anymore.  I’ll keep my current one around should
you ask me to debug it.
