This implementation avoids loading the entire file in memory.

So closing the fileHandle AFTER we've removed the original item won't be a problem? I'd imagine we would need to close it before deleting the file but I might be wrong.

This is basically just a file descriptor inside. I did this after moving it because we don't want to leave an inconsistent state if any of the move operations fail.

I wonder if this function should be executed atomically, so if there are multiple threads using this handler, this doesn't cause any issues (We don't do this in Android either)

That's handled by the fact that this type is an actor :)

Should we have a test making sure the file ends with a new line break?

I thought it wasn't that important to add an explicit test, as long as the other logic works as expected (appending an existing file, etc). What do you think?
