Comment-deprecate the undocumented rfile kwarg to WSGIHandler (not using the warnings module because this is a hot code path and also because DeprecationWarning is ignored by default under Py27 anyway) [skip ci]

Working towards improved release support (zest.releaser): compatibility with the pyroma setup linter and fix the issues found. Next up: the manifest.

Fix coverage numbers for top-level statements in __init__.py and friends. Also add some useful platform-specific exclusions.

Add a test for #651 and really fix #651 this time (another manifestation of the same underlying issue as #652)

Support coverage.py in the testrunner and coveralls.io

Add python 3.5 selectors test, and remove the devpoll selector under 3.5. also update the monkey documentation.

Honor the timeout argument to Popen.communicate if there is no way to communicate with the child. Fixes a Python 3.5 test failure; add the Python 3.5 subprocess test suite.

See the detailed changelog entry. This brings correctness, debugging,
and performance benefits. It further matches the already documented
and specified restrictions on application-provided header and status
line values.

Python 3.5 regression

Unify and simplify the implementation of Queue.get and Queue.put. Fixes #647 (add a test case for that scenario).
