  Changed paths:
    M .travis.yml
    M CHANGES.rst
    M setup.py
    M src/zc/zlibstorage/__init__.py
    M src/zc/zlibstorage/tests.py
    M tox.ini

  Log Message:
  -----------
  Close the underlying iterator.

Fixes #4.

Also add PyPy support.

Modernize the .travis.yml: sudo false, pip caching, same testrunner as
tox.ini.

Pin ZODB/ZEO to old versions because ServerZlibStorage is broken for
ZODB 5. Will address in a subsequent PR.
