I'm an equal opportunity patch employer: I'll take it from anyone.

That being said, I would open a new issue on the tracker
(bugs.python.org) outlining the issue (removing these/deprecating
them) and add me to the +noisy. There you can upload patches as you
create them, and we can all coordinate work and discussion there.

For the multiprocessing support - the first step is to identify why
it's being used and remove it (I'm head-deep in pycon talk prep, so I
haven't been able to look) and then replace the code. Second, I need
to make sure the multiprocessing.queue API does not have it's own APIs
for these (mp.queue is a clone of queue.queue) and deprecate those.
