There is actually an undocumented config directive "BufferedLogs On" which 
will do this.  I'm not sure how well it works.

You can also, of course, use a piped log program to do whatever buffering 
you want with your logs.

After the response.  This is necessary to allow logging of certain things 
that are only known at this time (like the length of time taken to send 
the response, for example).  It is not configurable.

mod_log_forensic will write information about the request both before and 
after the response.  But I'm not exactly sure why you want the log written 
before the reponse, so it is hard to tell if that will solve your problem.
