Sorry, I've posted the wrong link. It should have been:

Yes, we started discussing this functionality on the dev list some time ago,
but it wasn't finished. We certainly need some kind of a similar solution. I
may try to revive that thread in a few days.

It doesn't really offer a nice solution though, does it? It looks to me
like the best way to handle it is with Apache::Symbol, just like
Apache::StatINC did. It looks like you can just add this to your
Registry script:
use Apache::Symbol ();
@ISA = qw(Apache::Symbol);
Or maybe look at the code in StatINC and do the same thing in Reload.
This is only available for mp 1.x though.

Shoot, I glanced at that section but was thrown off by the word
'cache'. It didn't occur to me to think about exported functions in
that way. Thanks for the help, this all makes sense now!
