- SF bug #992389 bit me when I wanted to do absolute imports
  at the checker classes :/
  When the bug is fixed we can import absolute classes

- cache queue rework?

- document what checks are performed for each url type

- SF request #952051: is query considered in url cache keys?

- warn if overall size of page (including images/flash/etc.) is too big
  right now, the page size is only html content

- save downloaded pages

- error:
