Okay, thanks.  This shows that free_image does get called.

What image types did you try till now?  If you tried with only one
image type, please see if other image types exhibit the same problem
(i.e. that memory is not returned to system when an image is killed
and the image cache cleared).

If you already tried all the supported image types, I cannot think of
any reason but one: that the Cygwin implementation of malloc/free does
not return freed memory to the OS.  If this is the conclusion, then it
should probably be taken up with Cygwin maintainers on their mailing
list.
