Ok. So, apparently, gdb-mi has a set of "source files it has visited"
and treats other source files differently.

I see. When I find the time, I'll try diff-ing the code of gud-gdb and
of gdb-mi to find what magic the gud-gdb STOP button has, which makes it
have "a stronger interruption effect".
If I find anything, I'll report it here.
Thanks for your help!
