It sounds like my theory was wrong.

Does Emacs release the memory to system in general?  For example, if
you visit a very large file, then kill its buffer and type

  M-x garbage-collect RET

does the memory footprint return to the value it had before visiting
the large file?

(Btw, I hope you do all these tests in "emacs -Q"; if not, please do.)
