Another point to remember about using resistors as fuses is that unless the 
manufacturer guarantees the fusing current, time and prospective fault voltage, 
you haven't a clue if the results are repeatable from batch to batch - or even 
from resistor to resistor. A change in manufacturing process (or factory) can 
mean totally different results.
And if you test the part for fusing capability, you can't use it afterwards!
