Just like you had called req.register_cleanup() except that cleanup
handler is called on server shutdown like req.server.register_cleanup().

  register_cleanup(callable[, data])

    Registers a cleanup. Argument callable can be any callable object, 
the
    optional argument data can be any object (default is  None). At 
Apache
    child process termination, callable will be called with one 
argument, data.

    If errors are encountered during cleanup processing, they should be 
in
    error log.

Note that I have actually made a minor mistake in the code. In 
apache.py,
the prototype should be:

   def register_cleanup(handler,data=None):
       _apache.register_cleanup(_interpreter,_server,handler,data)

I used "args=()" which isn't technically correct but only in as much as
I used "()" instead of "None". I was thinking you could supply a tuple 
of
arguments whereas you can actually only supply a single argument. What I
did wouldn't have stopped it working though.

Anyway, you should be able to do:

   def shutdown1():
       apache.log_error("shutdown1")

   apache.register_cleanup(shutdown1)

   def shutdown2(data):
       apache.log_error("shutdown2 %r"%data)

   apache.register_cleanup(shutdown2,"data")
