Now that we have a good algorithm,  I'm open to adding this to itertools,
but it would need to have a name that didn't create any confusion
with respect to the existing tools, perhaps something like:

    anagrams(population, r)

    Return an iterator over a all distinct r-length permutations
    of the population.

    Unlike permutations(), element uniqueness is determined
    by value rather than by position.  Also, anagrams() makes
    no guarantees about the order the tuples are generated.
