This is done by 2 ways which both fit very well together: - We stop use LockRefPtrs. We also don't allow expansion of the m_channels member, by setting it to be a fixed Array of 2 IDEChannels. - More error propagation through the code, in the construction point of IDEChannel(s). This means that in the future we could technically do something meaningful with OOM conditions when initializing an IDE controller.
