Remember the "how can a debugger WRITE safely to variables" discussion
last year?  A variable may reside in some unusual memory segment, AND
may have been loaded into a register, AND maybe even spilled to the
normal stack temporarily.  Could be three different address spaces
valid for the same variable at the same PC address.  (And a debugger
that needs to update the value would need to find them all.)
