Description

I've been noticing snapshots that have corrupted data if you quickly delete the original contents after snapshotting. I've produced this in both cfuse and kclient and wrote a unit test, but the unit test seems to always pass. It's also possible that if you cross the client's buffer size you don't hit this issue. But I tried it with a 2.2MB file and consistently failed, while doing so with the unit test it continued to pass.
No idea what's going on, but I kept logs of both cases. Figure it out!
