Today, "it" happened again (not sure how many problems were are
discussing here, though).

I had been cleaning my web.de INBOX with Gnus.  Started Gnus, deleted or
moved some messages, shut down, and repeated.  Then I suddenly saw that
our problem was back, Emacs using 6GB or so.  The session is gone now (I
shut it down normally).  I'm sure that at least a significant part of
the problem materialized while using (more or less only) Gnus.

And here is that heap output you wanted:
