Note: "memo" is just testing constructing a string, to prove 
that strings are not hashed at create time, but memoized with 
__hash__(). The functions construct new strings each time, 
with some variant of:

    '24058098:33d2a96e-ffad-11e2-b14b-8acd18156acf' * m

Where m is passed into the test function.
