It seems to be easy to make emacs (under X) to consume more and more
RAM, which is never released, by making it display images.  A extreme
(in my experience) case is animated GIFs, try:

  - emacs -Q
  - M-x eww RET https://xenodium.com/emacs-zones-to-lift-you-up/
  - RAM consumption grows to ~600Mb
  - R (redisplay page): RAM grows to ~1100Mb
  - R (redisplay page): RAM grows to ~1752Mb
  - R (redisplay page): RAM grows to ~2222Mb
  - rinse and repeat: RAM never goes down
  - (image-cache-size) reports a modest 82Mb
  - Kill buffer:  high RAM consumption is still at its maximum, even
    after (image-cache-size) goes to 0

My impression is that this bad behaviour is not limited to animated
gifts, although for regular images i don't have a solid recipe: what i
observe is that running long sessions in term mode for days of continous
use in an xterm, RAM tops at about 0.5Mb, while running similar sessions
under X (using the same packages and doing the same kind of things
inside of emacs), RAM will steadily increase.  The only difference
between the two scenarios i can think of is that in X i sometimes
display images, mainly in eww and, sometimes, inside HTML email messages
rendered via shr.  I also observe that while it's pretty common for
emacs in an x term (either run directly or connected to a demon) to
release memory (i.e., to have its RSS decrease), that almost never
happens when running under X: there RAM almost never goes down, no
matter what.
