[issue18302] test_multiprocessing: test.support.import_module() does not ignore the ImportError on SemLock

Brett Cannon added the comment:

Because I removed ModuleNotFoundError; check the buildbot again and you will 
notice it is 8 changesets behind, most of which are related to the removal of 
ModuleNotFoundError.

Brett: Why did you close this issue? It still occurs on the buildbot:

[issue18302] test_multiprocessing: test.support.import_module() does not ignore the ImportError on SemLock

[STINNER Victor]

New submission from STINNER Victor:

test.support.import_module() catchs ModuleNotFoundError instead of ImportError 
since the following changeset:

changeset:   84106:c4d7228421df
user:Brett Cannon 
date:Wed Jun 12 20:12:30 2013 -0400
files:   Lib/test/regrtest.py Lib/test/support.py Lib/test/test___all__.py 
Lib/xmlrpc/server.py Lib/zipfile.py
description:
Move test___all__ over to unittest.main() and use ModuleNotFoundError

The problem is that multiprocessing.synchronize raises an ImportError if 
_multiprocess.SemLock does not exist:

# Try to import the mp.synchronize module cleanly, if it fails
# raise ImportError for platforms lacking a working sem_open implementation.
# See issue 3770
try:
from X_multiprocessing import SemLock
except (ImportError):
raise ImportError("This platform lacks a functioning sem_open" +
  " implementation, therefore, the required" +
  " synchronization primitives needed will not" +
  " function, see issue 3770.")

As a result, test_multiprocessing is no more skipped on FreeBSD 6.4, but the 
following traceback is written:

http://buildbot.python.org/all/builders/x86%20FreeBSD%206.4%203.x/builds/3771/steps/test/logs/stdio
