This is the only line that has been modified from the previous PR's. Namely it's self_xp->parser on 3.4. On the other branches it's self->parser due to argumentclinication.

Oh, Travis CI failed on a random failure:

======================================================================
ERROR: test_ignore (test.test_multiprocessing_forkserver.TestIgnoreEINTR)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/home/travis/build/python/cpython/Lib/test/_test_multiprocessing.py", line 3623, in test_ignore
    os.kill(p.pid, signal.SIGUSR1)
ProcessLookupError: [Errno 3] No such process

I scheduled a new job.
