Oh, thanks for that reminder. Actually I disabled parallel sphinx building temporarily [1], because it was making things hard to debug. But it looks like I only disabled it for the reference-manual building and not for the AllBuilder; I will try that next.

Once everything builds without parallel-build, I'll see if I can do the tweak that others mentioned, of using fewer processes for the docbuild.

On a side note, I'm pretty sure that this:

            except Exception:
                pool.terminate()
                if ABORT_ON_ERROR:
                    raise

in both places that it occurs in docbuild/__init__.py, does not work as intended. And then this messes up subsequent builds, and I get "not found" errors. This is partly why I (tried to) disabled parallel docbuilding in the first place. But I'll try to explore this in more depth and come back with some more details.
