Default Pros and cons of a GFI on a non-grounded circuit

Friend of mine is remodeling the kitchen in a 40's home. No ground circuit
to anything. He wants to add some GFI receptacles to the kitchen. Is this
a
good or bad idea? As far as we can tell, the wire to the kitchen area is
imbedded in plaster. Does not appear to be in conduit. The fuses are screw
in plug fuses.


It is *especially* a good idea to have GFI if there is no ground.
The only thing I'm not sure is, does the test button on GFI work without a
ground?


On the GFCIs I've looked at, the test button would connect a resistor
between hot on the load side and neutral on the line side. No ground
involved.
