How large is ``large''?  Can you please name the specific files you
used in these two experiments, if possible files that can be found on
the net somewhere?

I tried this with several image files on my system, and while I never
got as high as 39MB, whenever I kill the buffer and clear the image
cache, the memory usage goes back to the initial number, modulo a few
dozen bytes (which are probably due to Emacs internal workings
independent of images, because I get such variations even if I just
invoke TAB completion).

I tested this in the native (MinGW) Windows port, so maybe what you
see in the Cygwin port is specific to Cygwin memory allocation and/or
its interaction with Emacs.  Still, I'd like to repeat the experiment
with precisely the files you did.
