> When a being written file or it's ancestor directories is renamed, the path
> in the file lease is also renamed. Then the writer of the file usually will
> fail since the file path in the writer is not updated.
> Moreover, I think there is a bug as follow:
> # Client writes 0's to F_0="/foo/file" and writes 1's to F_1="/bar/file" at
> the same time.
> # Rename /bar to /baz
> # Rename /foo to /bar
> Then, writing to F_0 will fail since /foo/file does not exist anymore but
> writing to F_1 may succeed since /bar/file exits as a different file. In
> such case, the content of /bar/file could be partly 0's and partly 1's.
