I thought about the possibility of fixing existing memory targets to 
handle misaligned access, either by implementing support, returning 
sid::bus::misaligned, or whatever else might be appropriate. However it 
occurred to me that this would require implementors of all future memory 
targets to be aware of potential GDB access of this type. This just 
seemed like something that will always work regardless of the 
implementation of the downstream memory.
