I meant to explain that point on "why". Self modifying by definition #1
matters if you're looking at I-cache management, but address space ID numbers
may take care of things. For #2, you're probably going to be doing explicit
I-cache invalidation.
For #3 and #4 (which are subsets of #2) the same would be true if they were in
current use, but they generally aren't.
