I explained it badly.  By confused I mean that these signals cause the
debugger to stop and print the fact they they received SIGCONT.  I just
want these signals handled by the application and not intercepted by the
debugger, I played with "handle SIGCONT" but I didn't manage to get it
to work as I wanted ( I tried: pass noprint nostop)

Thanks for the hint, this is a much better way to do it.
