Assuming that I can verify that a bunch of POST requests are in fact logically independent, how can I set up HTTP pipelining using python-requests and force it to allow POST requests in the pipeline?

Does someone have a working example?

P.S. for extra points, how to handle errors for outstanding requests if pipeline suddenly breaks?

P.P.S. grequests is not an option in this case.

Pipelining requests can be done with the builtin httplib, but only by accessing the connection and response objects below their public interface. This snippet demonstrates.

Edit: updated version for Python3: https://github.com/urllib3/urllib3/issues/52#issuecomment-109756116
