the so-called 'reloaded' workflow.

  - Ensure all defstates have :stop directives
  - Ensure tests always start from a fully-stopped point, so they
    do not accidentally run against the 'dev' db or other 'dev'
    resources.
  - Throw away poorly reasoned about cats.user functionality. Just
    provide a single function to restart the dev system from the
    REPL.
