Ugh. I think it's a requirement; without it:
- if we set the flag that allows the client to turn off
sillyrename, then users will see a regression (ESTALE after
clean shutdowns in situations we previously guaranteed safe).
- if we don't set that flag, we don't get to turn off client
sillyrename. The only improvement is that we avoid ESTALE
after crashes on files unlinked by a different client than
held it open. I don't think that's very interesting on its
own.
