[Checkins] SVN: zc.buildout/trunk/src/zc/buildout/testing.py environ.pop is not equivalent to a get followed by a del. :(

Log message for revision 69989:
  environ.pop is not equivalent to a get followed by a del. :(
  
  Added an environment variable hack to cause the buildout to use a
  local empty index when running tests. This allows most of the tests to
  be run when offline and doesn't slam pypi at other times.
