It might be useful to create two Process::CoreFileMemoryRanges lists: one for 32 bit and one for 64 bit and have a variable that keeps track of what was already added:
```
uint64_t ranges_32_size = 0;
Process::CoreFileMemoryRanges ranges_32;
Process::CoreFileMemoryRanges ranges_64;
```
Then we can add regions to each list as needed below without having to remove anything from the `ranges` list below?
