Not only that but it will provide a shunt which allows one to measure 
the current.

Most any time I think the circuit can stand it I put 100 ohm resistors 
inline. Provides a bit of protection but also provides a location I can 
easily measure voltage across the resistor to "see" the current. Also 
because I often draw the schematic, lay out the PCB, and have a few 
boards built before powering the circuit the first time.
