+So after some debugging, I have seen the issue is that the httpd process
+ignore the SIGTERM sent by the main apache. 
+
+It seems to be caused by mod_wsgi, and commit 1051, that tell to
+mod_wsgi to let a software register  a callback for signal. Since viewvc
+was sending messages in the log, I disabled the check. Since this broke
+apache, I reenabled it now. 
+
+A proper fix for viewvc should not be too hard to do ( just no time ).
