Ah right.  Hmm, so then why the crawling?  Is that because of the busy
waiting style of the messaging system then?  That really needs to be
addressed any way...  I think this should do the trick for AllegroCL,
but I can't try it out just now:

(defun make-event ()
   ...
   #+allegrocl (mp:make-gate nil)
   ...)

(defun event-wait (event mutex)
;note: this function should appear inside with-mutex block
   ...
   #+allegro (progn (mp:process-wait "wait for message"
                                     #'mp:gate-open-p
                                     event)
                    (mp:close-gate event))
   ...)

(defun event-notify (event)
   ...
   #+allegro (mp:open-gate event)
   ...)
