While on the subject of build times, another frustrating delay happens
with the generation of .texi intermediate files from those doc files
whose source is .org.  There are two of these, modus-themes.texi and
org.texi.

The first isn't too bad, because it's small, but org.texi is taking
~20 seconds to generate on my machine (which is doing nothing else at
the time) plus, perhaps, 3 seconds for org.info.

Would it perhaps be possible to set the documentation generation going
at an earlier stage of the bootstrap, in effect spreading out the
slowness over the entire battery of processor cores?
