Yeah. At the moment tempbuf.el works quite well for those of us who like
their buffer lists neat and tidy, but it is necessarily a kludge. I
applaud the search for something better.

(I have actually in the past wondered if it would be nice to have
buffers structured into directories somehow so you could normally ignore
unrelated buffers, but have come to the conclusion that better
navigation is the answer. For me, GNU GLOBAL-driven semantic.el
navigation via CEDET and Icicles-based switch-by-content has sufficed to
control even Emacsen with thousands of buffers open... though this is
mostly Semantic's fault, since it opens files to parse them and often
forgets to close them again. This is something that would definitely
benefit from a temporary-buffer marking, since you certainly can't use
the mode of such buffers as a hint.)
