The test_HTTP_200_OK_METHOD_ssl may fail from time to time with various reasons:

For the last case if raise the original exception instead of aiohttp.OsConnectionError the traceback becomes more verbose:

To guarantee reproduce run:

watch -e nosetests --tests=tests/test_client_functional.py

and wait for a while. Not sure for now where the issue is: in test_util.run_server or somewhere deeper, but may be you have quick idea about what could be wrong.

Python: 3.3.5 / 3.4.1
aiohttp: 0.8.2 @ #2b19a85e3b
tulip: 3.4.1

It might be timing issue. Could you test this against master?

[kxepal]

Cannot reproduce any more after 388b828 commit. Looks like it's fixed now.
