A question about the post_config phase mod_perl handler

[Boysenberry Payne]

In the example at:
http://perl.apache.org/docs/2.0/user/handlers/ 
server.html#C_PerlPostConfigHandler_

the PerlPostConfigHandler subroutine returns Apache2::Const::OK.

I was wondering if it mattered what it returned, and if so, what are  
the alternatives?

Just curious really...
