i think is very usefull to have this in production environment... to debug probleme without
interupting production... in only up the log level with reload...
with strace you must restart apache with strace...and for desactivating it you must restart...
in some production environement is not acceptable...

I think you'd be far better off with a generic trace such as strace.
They're made for precisely this kind of thing.

Having said that. what you could do with the hooks is to wrap them
in functions that add logging.  To do that with apache logging would
require the APR macros to be masked out.  Since you'd be adding 
overhead to everything the server does, you'll never get it accepted
into the main source tree, unless you can at the very least make it
conditionally compile.
