I just started a voluntary career break, but I'd like to stay active.

I looked over the TODO file, but I'm not sure which item to tackle.
Could you recommend an item for someone new to the project?

One thing that would be super cool would be multi-threaded xslt
processing (e.g. for chunked document output). Unfortunately again, this
is not trivial at all. But any speedup for xslt processing would be
great. The docbook xml -> html step in gtk-doc is so slow that most
developers to api-doc generation off still :/

   Processing chunks in a subthread is an interesting idea. The
stylesheet is read-only from a transformation process POV so that
may work without too much crazyness...
   Two suggestions:
    - what about a reduced simplified DocBook XSLT for gnome, using
      only what you care about, that could be packaged and registered
      in the XML Catalog, and potentially simplify the processing
      running an xsltproc -v on a number of documents and grepping the
      results may lead to interesting results (but that will be
      voluminous !).
    - check where the time is really spent, is that in the XPath engine ?
      I used to kcachegrind transformation on DocBook and try to find
      what were the hotspot, I think I had that flattened at the time
      (6-7 years ago) but with new stylesheets it's possible there
      is new troubles, as was pointed out recently.
