I've ascertained that it is in fact a problem: this thing is sent
directly on the wire, and it gets memcmp'd, so having padding bytes in
it is going to cause trouble.
Also, if you reboot and update the kernel to add this change all old
file handles will quit working; this probably doesn't matter though.
