Eventlet 0.11 bug fix release

[Sergey Shepelev]

Hello. Eventlet 0.11 is available.
http://pypi.python.org/pypi/eventlet/0.11.0

This is a quick bug fix release featuring:
* ssl: Fix busy loop in socket.sendall(). Thanks to raylu.
* zmq: Return linger argument to Socket.close(). Thanks to Eric Windisch.

What's next: zmq .bind(PUB) busy loop fix, modernized documentation, contributor friendly PEP-8 and style fixes.

We still have lots of work to do. We need smart people like you to help with these:
* For easy start, join discussion on project development path. Nose or py.test? Which pep8 messages to ignore? https://plus.google.com/u/0/109869205442495270563/posts/BhRip2sG128
* Always need various environments to run tests. Automated build agent would be super awesome.
