Beginner Multiprocessing Question

I'm trying to run a really simple multiprocessing script but I get an error that says "AttributeError: 'module' object has no attribute 'f'.  *See script below.  Every time I try to run any sample script w/ a multiprocessing process, I get the same error.  I'm on Windows 7, with the stock Python 2.6 install that comes with ArcMap 10.0.  I also tried this on a machine with 10.1 and Python 2.7 and got the same error.

I got the script from here:


*The script is:

from multiprocessing import Process

def f(name):
    print 'hello', name

if __name__ == '__main__':
    p = Process(target=f, args=('bob',))

Full error output
