[issue18356] help(numpy) causes segfault on exit

[Torim]

Torim added the comment:

I would add even the linked solution from StackOverflow.com does not work reliably for me. Try to get at the end of numpy document - text vanishes and possibly lose chars displaying in terminal. Need to reset it.

Modified pydoc's pipepager method this way:
def pipepager(text, cmd):
    """Page through text by feeding it to another program."""
    #pipe = os.popen(cmd, 'w')
    import subprocess
    pipep = subprocess.Popen(cmd, stdin=subprocess.PIPE, shell=True)
    try:
        #pipe.write(text)
        #pipe.close()
	pipep.communicate(text)
    except IOError:
        pass # Ignore broken pipes caused by quitting the pager program.


Works for me so far, although the exact cause of issue with the stock/default pydoc is still not known.
