I did wonder if one way around this problem might be to define that a  
directory which contains
per-file ACLs has a directory ACL which conveys no permission at all.  
There could then be a separate 'default' ACL managed via the new RPCs.

A client which sets the first per-file ACL in the directory would  
clear the directory ACL, having first warned the user that doing so  
will result in legacy clients being unable to access files in that  
directory.

Thoughts?
