// Make sure the deletion event gets reported in the following scenario:
// 1. Watch a file.
// 2. The initial stat() goes okay.
// 3. Something deletes the watched file.
// 4. The second stat() fails with ENOENT.

// The second stat() translates into the first 'change' event but a logic error
// stopped it from getting emitted.
