* Add a warning for misconfiguration.
As specified in the docs, by default the settings result in a configuration where slow tasks that run for more than 60s cause repeated running of tasks, which has caused a few issues. This warning doesn't change the defaults, which would be a marge larger change, but instead provides a, hopefully, helpful message to the user.
