PendingDeprecationWarning: dist() and linux_distribution() functions are deprecated in Python 3.5 and will be removed in Python 3.7

This is caused by issue 1322. I'll fix it.

Interesting, I ran the test suite twice before commit the patch. I will take a look, thanks!

Here is a patch.

An unrelated failure:

$ ./python -Werror -m test test_slice
[1/1] test_slice
test test_slice failed -- Traceback (most recent call last):

  File "/home/berker/projects/cpython/default/Lib/unittest/case.py", line 153, in handle
    DeprecationWarning, 3)
DeprecationWarning: callable is None

The patch LGTM. But what to do with this code after 3.7? And why not to do this right now?

Ah, this is issue24134. Thank you for reporting this.

It's on my TODO list, but I'll probably won't have time to work on in it before beta 1.

Thanks for the review!
