Depends on where you are. On AFS, for instance, stat() calls aren't
cached on the client, so they're potentially much slower (!) than
read()s; for that reason, checking the inode signatures is exceedingly
slow there, and so this optimization will be a very substantial gain.
(Yes, I realize that AFS is not a common case).
