    Kill processes when cleaning up namespaces

    This patch will kill processes that are listening on any port/UNIX
    socket within the namespace to be cleaned up. To kill them it will
    issue a SIGTERM to them (or to their parents if they were forked) and,
    if they don't die after a few seconds, a SIGKILL to them and all their
    children.

    This is intended for those cases when there's no specific cleanup and
    serves as a fallback method.
