So I trace this call back to dc255b24e30a (Chong Yidong, 2007-05-21). At
that time 'image-flush' was called 'image-refresh' with the same
functionality of uncaching an image given its spec.
Before that, the whole image cache was cleared (fcfc4732e0d9, Chong
Yidong, 2006-02-09). I did not find a bug reference and I still don't
understand why it is/was needed.
