in reply to Mason subroutine not relefecting changes

IIRC, it's not Mason causing the problem, but mod_perl, which caches the Perl to make things run faster. In my limited experience with Mason/mod_perl, what I do in this kind of case is just restart Apache, which clears the cache. There may be a better way, but I know this one works.
