* User creates a large ~5MiB commit
* This explodes into a 250 MiB unified diff
* The commit can be parsed with a "reasonable" amount of memory and the script/daemon gets killed by the OS. Then the task backs off and runs off to get killed later I'm not sure how much this particular commit would need but ~8 GiB was insufficient.
* User is sad that their diffs are not getting closed.
Ideally this would take less memory but there will probably always be bigger diffs on the horizon. Some way to skip parsing the diff (automatically?) if is 'Too Big' is one possibility.
