Comment(by bonefish):

 Eliminated a possible cause in r30605. When a mapped file was shrunk,
 pages could be freed without removing their mappings. That would fit the
 reported case where the mapping was in a "libtracker.so_seg0ro" area, *if*
 libtracker.so was re-compiled and a program using it was still running.
 The other reported cases (TextSearch, nc) don't seem to fit, though. So
 I'm leaving the ticket open. I've introduced a new panic()ing check in
 r30606 which will hopefully trigger earlier.
