OpenIndiana failure looks like a resource management issue in ctypes:
======================================================================

Ubuntu LTS failure still puzzles me:

======================================================================
FAIL: test_with_pip (test.test_venv.EnsurePipTest)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/opt/python/3.x.langa-ubuntu/build/Lib/test/test_venv.py", line 289, in test_with_pip

subprocess.CalledProcessError: Command '['/tmp/tmpwsahapjn/bin/python', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 3

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/opt/python/3.x.langa-ubuntu/build/Lib/test/test_venv.py", line 295, in test_with_pip
    self.fail(msg)
AssertionError: Command '['/tmp/tmpwsahapjn/bin/python', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 3

**Subprocess Output**
Could not find an activated virtualenv (required).
