My main motivation is the Don't Repeat Yourself principle -- I'd like to 
be able to find out the name of the pidfile without duplicating its name 
and location anywhere in the configuration, and since Apache already knows 
it, I can't think of a reason mod_perl shouldn't expose it.

But either way, life will go on. :)
