New description:
When building the PDF documentation, if there is problem while running
`latex`, then the docbuilder just hangs forever ''after building all
documentation''. There is no obvious clue what the problem is apart from a
message like the following (example from #9107) in the log file:
{{{
! LaTeX Error: Too deeply nested.

Type H <return> for immediate help.

Exception in thread Thread-6:

This looks like a bug in the Python `multiprocessing` module.
Also: the docbuilder should use $MAKE instead of make.
