It is a mutex that protects the mini-buffer from concurrent accesses.
Only one thread can use the minibuffer at a time.

No, I don't have a patch, I have just experimented with "(run-in-thread
gnus)" to verify it loads correctly in a separate thread.


Also we have to mention the two new macros:

(defmacro with-new-thread (&rest body)) -- BODY is executed in a new
thread.

(defmacro with-critical-section (mutex &rest body)) BODY is executed
after MUTEX is locked and automatically released on exit.
