I've always thought that was a bad misnomer. Isn't it just an alternative
memory-mapped address space pretty much like main memory (regardless that the
mapped devices may have some fairly non-standard characteristics)? Certainly
from the compiler's point of view it's got to count as "memory"; it's
somewhere values come from and go to and are "externally visible".
