if it's safe or not call add_rr_param() from branch_route is an already
debated subject. See:
Shortly you may not call it from failure route or from branch route
triggered from a failure route(so no serial forking. But you can safely
use it from a branch_route triggered by a request route.
This problem will be fixed as soon as the cvs is forked for the new
regarding the future behaviour in failure route - if you do
add_rr_param() in branch route, this change will not be visible in the
failure_route - actually any change from branch route will not be
visible in failure route.
