Again, I think this is an issue with the expectation of
RCArray. You cannot *save* a ref to an array element, only a
ref to the array itself, because you lose control over the
reference count.
What you need is a special RCSlave type, which is reference
counted not to the type of its *own* data, but to its parent's.
In this case, a RCArraySlave!(T) holds data of type T, but a
pointer to an RCArray, which it decrements when it gets
destroyed. This could get expensive, with an extra pointer per
instance than a regular T, but it would probably be safe.
