[4.x]: Image transforms via queue - memory leak?

What happened?

Description

Not sure if this is a bug or just a matter of configuration.
We are using image transforms for our assets, they are handled via queue. We noted, that the job Generating pending image transforms needs very long for 75 images and gets canceled due to queue ttr. We already set the limit to 6000 which is still not enough. I am aware, that image transforms are expensive and it´s ok that it needs some time, however, our actual issue is, that the job is not freeing up memory after transforming or checking an image. As soon as the job gets canceled (after 6000) the memory usage drops. To me, the memory usage chart looks like it keeps already transformed images open and moves to the next one. As soon as the job timed out, memory usage dropped back to normal.

We are using this image: craftcms/cli:8.1@sha256:1f972a7493e056a21bcc4604c0dd44c497797d9fd2fecb61f5919c263228f2ab

Steps to reproduce

1. Create Image Transforms
2. Upload 20+ Images
3. Watch Generating pending image transforms
4. Memory Usage increases

Expected behavior

Memory on server should be freed, after an image within one job gets transformed before moving to the next image within the same job

Actual behavior

Memory on server grows until job get´s killed or server runs out of memory
