  of most plexus components has been to avoid instance state like the plague.
  With the current parameter passing model of mojos, this will not be possible,
  particularly when we move mojos to a singleton instantiation model, and then
  run a reactorized project...the successive calls may leave behind configuration
  artifacts from invocation to invocation.
