ARM Raspbian 3.x:
https://buildbot.python.org/all/#/builders/424/builds/294

I don't understand why the test started to fail at build 294 which only has one new change: commit 2165cea ("bpo-29566: binhex.binhex now consitently writes MacOS 9 line endings"). It seems to be unrelated.

I failed to reproduce the issue on Linux.

The test failed on many 3.x buildbots. Other examples:

• PPC64LE Fedora Rawhide 3.x: https://buildbot.python.org/all/#builders/455/builds/226
• AMD64 Windows10 3.x: https://buildbot.python.org/all/#builders/146/builds/295

The 3 mentionned buildbot workers are back to green, so I close the issue.
