Jython bug in CSM 2021x

[bobsimmons88@hotmail.com]

CSM 2021x uses jython 2.7.2. Trying to import socket.py in one of my jython macros causes an error "Unable to import name Iterable". The bug seems to be in _socket.py with the line:

from collections import namedtuple, Iterable

Digging into the issue, my workaround was to split the import into two lines:

from collections import namedtuple
from _abcoll import Iterable

Looking at collections.py, which imports _abcoll.py, this shouldn't be necessary; the comments in _abcoll.py make clear that the intent is that everything is to be imported from the collections module.
