SEQUENCE OF EVENTS
==================
- /file has inode 1.
- Thread A opens /file and creates the in-memory inode 1.
- Thread A closes its file handle and enters the code path to destroy the in-memory inode 1, but is preempted after releasing inode_lock and before calling inode_orphaned.
- Thread B opens /file and re-creates the in-memory inode 1.
- Thread B renames /file2, which has inode 2, to /file. This removes the last reference to inode 1 in the database.
- Thread A wakes up and goes to finish the destruction of inode 1, which removes it from the database since it has no more references.
- Thread B calls fstat on its open handle to inode 1. This fails because it's gone from the database.
