Be strict in our AnyEvent usage
  Cache SQL-statement handles.
  Only output if ENV DEBUG=1
  Add --debug.
  Don't recreate the redis-parser on each network event.
  Optimization - Don't DELETE & INSERT.

  Instead we use INSERT OR REPLACE - which cuts down the queries
 on an insert by 50%.  Win.
  Default to nonsafe operations  because we love the dark-side.

  This speeds up the get/set combo by several orders of magnitude.
