In mod_perl 1, you can only store pnotes at a request level, so a
subrequest has separate pnotes.  This meant you would need to lookup
the parent request ($r->main) to get your pnotes.  In mod_perl 2, you
have the option of using pnotes on a connection level instead of a
request level.

I recommend pnotes any time you need to pass data between mod_perl
phases or store something that has to be cleared at the end of every
request.  It's generally more reliable than using globals and manually
clearing them in a cleanup handler.
