If you don't need a request body in your module, it's not clear 
why at all you are trying to read it.  If, in contrast, you do 
need the request body, you shouldn't try to do the real work till 
the post_handler is called.

Technically, you can use multiple access-phase handlers to handle 
things, as long as proper order is maintained by using flags set 
in post_handler.  But there is no need to use multiple handlers to 
do this, as there is no real difference as long as you anyway 
maintain flags set in post_handler.  On the other hand, if you 
indeed using a stub post_handler, it means that things are working 
by chance.
