This is being set from a Windows client by the way (not using setfacl on the linux box or anything).

I think this is the Windows client code recursively setting
ACL's in everything under the directory you're changing.

I'd be interested in a network trace showing the difference
between doing this against a Windows server vs a Samba
server.
