(not a nak, just a tangential thought)
It would be cute if you could just insert a "trace this access
and pass it through" container MemoryRegion at an arbitrary
point in the memory region hierarchy. That would let us do
"trace accesses to device X" without device X having to
have boilerplate tracing code in its read/write functions.
