If it does, it certainly sounds like a very bad bug.

However, according to the documentation for icacls
(http://technet.microsoft.com/en-us/library/cc753525(WS.10).aspx), you
should use "/t" to get it to traverse into subdirectories, and clearly
it's not doing that. So I wonder why it would go across the whole
filesystem - might tbere be a  bug in icacls?

Or maybe it has something to do with inheritance? The way
inheritance-permissions works on ntfs is, um, let's call it
interesting.  Maybe it needs to specify the (NP) flag to not propagate
inheritance or something?
