  Here is what I get in the trace buffer : 

======================================================================
1 -> doc-view-kill-proc: 
1 <- doc-view-kill-proc: nil
======================================================================
1 -> doc-view-kill-proc: 
1 <- doc-view-kill-proc: nil



  But I cannot interpret that !
