But the title-problem showed that having many buffers (like 200 or so)
can cause this buffer-name-lookup to take a long time. The worst part
is that having 200 buffers is not particularly excessive: I regularly
have Emacs session with a hundred buffers or so. So we should avoid
this lookup loop whenever necessary.
