This happens to me all the time, but I don't recommend losing any
sleep over it.  It's very easy to delete the unwanted buffers (e.g.,
via "C-x C-b").  One does such cleanup anyway, when one finishes
working on some issue, right?

Emacs copes with many buffers just fine, so I wouldn't invest any
significant energy in getting rid of some of them using some
heuristics that will certainly misfire at some point.  Emacs should
only automatically kill buffers that it creates for its temporary
jobs, not buffers created by user commands.
