The appropriate way to get a rolling restart is to restart the web framework cart. Although we can do better here as well. Will keep the bug but not a high priority for now.
Set the tw_reuse flag for better behaviour. See bug#1110035 for details. *** This bug has been marked as a duplicate of bug 1110035 ***
