I've spent some time investigating memory leaks in my repo SUPERCILEX/clipboard-history#41 and have found a bunch of different caches in the egui codebase that slowly grow over time. These should all be cleared when the app is sent to the background.

I've dumped the big offenders below, but I fear they're not the root cause as re_memory isn't tracking anywhere close to the amount of memory I'm seeing with ps:

[egui/src/main.rs:372:13] stats.fully_tracked = CountAndSize {
    count: 35,
    size: 10376708,
}
[egui/src/main.rs:372:13] stats.stochastically_tracked = CountAndSize {
    count: 165,
    size: 97960,
}
[egui/src/main.rs:372:13] stats.untracked = CountAndSize {
    count: 12565,
    size: 595686,
}

This sums up to ~11MB but in ps I see ~400MB. I'm guessing most of it is from mmap allocations, but I'm unfortunately not sure how to profile mmaps.

CountAndSize { count: 1, size: 8388608 }
