In the change log, I found this:

     * [GN] Thursday, Jun 19 16:03:23 PDT 1997
       Minor enhancement to scheduler to make debugging easier by using
       the uid_ field of each event: positive uid_: inside the scheduling
       queue negative uid_: NOT in the scheduling queue
   

Hope this helps?
