Make theme safe for parallel reading?

[pitrou]

When trying to run sphinx-build with -j16, I get the following warning:

WARNING: the python_docs_theme extension does not declare if it is safe for parallel reading, assuming it isn't - please ask the extension author to check and make it explicit
WARNING: doing serial read

If you want to test it out and see if it's fine with parallel read, I'm happy to merge a PR to add this.

What is required to declare it safe? Not a Sphinx theme expert :-)

Seems to be covered here http://www.sphinx-doc.org/en/stable/extdev/#extension-metadata

Ok, I tested it on the CPython docs and it worked fine.

Cool, want to send a PR?

Hmm, I've just deleted my python-docs-theme clone... AFAIR it's just a matter of returning the required dict from setup() in __init__.py.

No worries, I'll make it happen.
