[Bug 902182] Re: spurious failure of test_readv_with_adjust_for_latency(HttpTransport_urllib, HTTPSServer_urllib) on armhf

[Vincent Ladeuil]

Just looking at traceback, this happens during the test tearDown.

Basically, this should be an EBADF exception which would be correctly
ignored at this point.

Instead, we get an AttributeError. This rings a bell about some python
version not handling the ssl sockets correctly (i.e. raising EBADF when
the socket is closed and lose its bound methods) so maybe the python
involved there didn't get the right fix...

Does someone remember better than me ?
