I have outlined a failure scenario for you as a reply to v6 ;)

Question to all: would it be feasible to limit the size of a single module's
.text + TOC to let's say 8MB, and place modules at 10MB granularity? Then it
would be unambiguous: exactly iff the high 40 bits of (TOC-LR) are zero, both
belong to the same module.
