The fact that the memory isn't marked free doesn't mean it is unusable. 
Tried in Gimp 2.10 on Ubuntu:

- load 5 20MPx Jpegs: memory is 1.35GB

- close all: memory still at 1.35GB

- load them again: memory is 1.4GB

- close all: memory still at 1.4GB

- load them again: memory is 1.4GB

- close all: memory still at 1.4GB

So the memory seems reused...
