Change _KnownGraph.parents to be a tuple rather than a list.
We know the size as soon as we walk to a map entry.
This way, we save a malloc, and have slightly smaller objects. Not a huge
difference, but a small one.
This changes KnownGraph(OOo_parent_map) time from 922ms down to 848ms, or
about a 10% savings for __init__ time.
