elasticsearch.helpers.parallel_bulk() hangs forever on Python 3.7.0

See original GitHub issue

I haven’t had a chance to dig into what’s new in Python 3.7.0, or how elasticsearch.helpers.parallel_bulk() works. But for some reason, it hangs forever on Python 3.7.0.

elasticsearch.helpers.streaming_bulk() works fine on Python 3.7.0, and my app isn’t indexing-heavy, so I’ve just switched to streaming for now.

I submitted a pull request. I am able to run the tox tests with it, though with concurrency bugs, there is always the chance that it doesn’t fully address the underlying problem. I see the symptoms, but did not fully root cause it. It could be that any blocking during teardown could cause the problem, and increasing the queue size just reduces the chance of that happening.

I’ll be testing out a larger pool size on my installation to see how the change affects real-world runs, and if hangs still occur occasionally.
