I see the distinction; I just don't see it as hiding. refcount_t will very much generate a splat indicating things need fixing, the leak simply ensures that it doesn't get worse from there on out. Anyway, if the code already needs to handle that failure case, such as inc_not_zero() usage, then there is indeed no additional complexity.
