The "ownership" metaphor has this defect: It's not like property, which has
only one owner at a time. The concept is, instead, "I need to keep a claim on
this object, so it doesn't go away without my saying I'm done with it."
So -release doesn't _give_ ownership of the object to anything else. The
"anything else" uses -retain or creation to _take_ ownership (maybe think of it
as "responsibility") for the object if it is interested in it.
