Permissions are cached during access. I'm not entirely sure, but I
believe I once noticed that the hoard daemon accesses objects with the
permissions of whoever executed the 'hoard walk' command (it should be
the user that originally added the hoard entry), so that 'root' will
have permission to modify the object, but your local user-id only has
System:AnyUser priviledges which are insufficient to actually do any

I'll try to read through the hoarding code today to see if I can
identify any culprits of this identity confusion.
