o BUG FIX: If the package was only loaded but attached, the cache 
  root path would default to ~/.Rcache/, which in turn could cause
  that path to be create without asking the user.  For instance,
  R.cache::loadCache(list()) would do.  Thanks to Kurt Hornik at
  Vienna University of Economics and Business for reporting on this.
