Bruce,

Thanks a lot -- I was aware of this.  This is exactly the same code idea
as the one in NFS's rename, and you cannot rename an open file at the
moment.   

The dentry stuff is tricky, but we'll find a better way.  

Have you seen any "still has aliases" messages?  It was my target to first
get those under control and then fix this issue.

Thanks again!

Peter
