AFAIU, the problem only exists with ResizableBuffer? We could do the following: - add a new Buffer member counting the number of exports (default 0) - in SliceBuffer, increment the parent's number of exports - in ~Buffer, decrement the parent's number of exports - in PoolBuffer::Resize(), return an error if the buffer has any exports (this is how Python buffers work, for the record) What do you think?
