So what was the problem there?  How did 'buffer-list-update-hook' get
invoked in such a wild manner?

This alone qualifies as a bug IMHO.

I think that creating a new temporary buffer should always be the
exception and never the rule.  Does the point moving happen in the
treemacs buffer or in that of a plain (probably git-controlled)
buffer?
