My suggestion would be:
a) Make KMountPoint return true for probablySlow for your path (if does not
b) Make the file ioslave honor KMountPoint::probablySlow for those kind of
"expensive" operations (also i think there's a way to tell kio that you want
slow operations even if you're in a network)
Note i'm not an ultra expert on the field so i may be saying silly stuff :D
