Yeah. Well, I used a recursive algorithm, with can be painfull if there
are mang things to parse.
Anyway, I didn't notice it, because there was a major performance regression
that happened recently that it is affecting all my sphinx builds: trying to
compile stuff in parallel with SPHINXOPTS=-j5 is crashing with:

I had to change my build scripts to remove parallel build, with increased
*a lot* the building time. So, right now, I just go out to take a coffee
or two when building documentation, as, without -j (even without this
patch series), is really slow.
If someone wants to look into it, the breakage happened by the time
I upgraded to Fedora 27 and Kernel 4.14 was released. Yet, I'm using
pip for Sphinx.
So, I dunno what's the culprit. I didn't have time yet to investigate.

Thank you!
