I tried these, but testing it with (setq inhibit-modification-hooks t)
did not give anything in the log file, so I suspect I won't ever catch
anything.

If I use
(gdb) watch globals.f_inhibit_modification_hooks
instead, then I get *a lot* of output in the log file. AFAICT, it's
mostly (if not always) because of signal_after_change or
signal_before_change which both issue "specbind
(Qinhibit_modification_hooks, Qt);" at some point.
