"Luckily" here, it seems that (usefully) increasing the number of cores
is not that easy, so this future is still a bit further.  But I'll note
also that concurrency is not solution for parallelism.

IOW if we want to take advantage of tens of cores in Emacs, we have to
think very differently.  A language with STM or with "communicating
agents" won't cut it, I think.
