That was my best idea, given my understanding of mod_perl, but now i'm not as sure. I just tested what I did above and got an error that wasn't present in the apache logs. The interface is the same as any other mod_perl handler:

sub handler {
    my $r = shift;
    my $err = ErrorTracker->new;
    
    # ... setup stuff

    my $args = validate_args($r, wrapped_handler_args());

    $r->content_type('text/plain');
    wrapped_handler($r,$args,$err);


    # shutdown / error handling stuff
    return $err->apacheStatus();
}


sub wrapped_handler {
print "inheritance is broken";
}

sub wrapped_handler_args {
  return {};
}
