      Solution: files are stored in Google App Engine blob store.
    - run the tests on all the implementations available for us.
  + - usocket test suite might need manual configuration,
  +   see their README. Distinguish the case 
  +   when the manual configuration hasn't been
  +   performed and return :no-resource status.
  + - For all the libraries which need manual configuration
  +   (cffi, usocket) provide giding message to the
  +   user how to configure them.
