  • The downside is the reference counting overhead, that the reference counting for ccw devices becomes more complex, in a sense that we need to pair the calls to the aforementioned functions for it to be correct, and that if we happen to leak, we leak more than necessary (the whole ccw device instead of just the genpool).
