Cool!

Also, I should have mentioned that I didn't trace the function
`org-element--cache-key-less-p' because when I do so, Emacs stays locked
even when I send it the signal SIGUSR2. However, this function appears
in the backtrace produced by `xbacktrace' in a gdb session if I call it
during a lockup.

My guess is that the lockup happens in `org-element--cache-key-less-p',
called by `org-element--cache-process-request'.

Best,
