I didn't look at buildbots recently, and I don't have access to FreeBSD, so I 
just close the issue :-/

Here is another one on koobs-freebsd10: 
http://buildbot.python.org/all/builders/AMD64%20FreeBSD%2010.x%20Shared%203.x/builds/4809/steps/test/logs/stdio
 test_handle_accept was fine this time.

And this one is from koobs-freebsd9:

[Martin Panter]

Martin Panter added the comment:

I think I have seen these kind of errors pop up randomly on various tests on 
Free BSD buildbots (at least in the last few months or so).

Are the buildbots so overloaded that they drop localhost connections? Or are 
localhost TCP connections generally just that unreliable on Free BSD? Or is 
something else going on? I’m not faimilar with the OS.

This only seems to affect 3.6, not the equivalent 3.5 buildbot.
