Block the signal handler. When you connect a signal handler, you
get a numeric ID for that connection. Pass this to
->signal_handler_block() before calling the function that causes
the signal, then pass it to ->signal_handler_unblock().

What Iâm not sure about is the exact mechanics of this; does one
need to make sure all emitted signals have been processed before
reconnecting, or is it enough to just block it during the call
which emits the problematic signal? Someone from the team will
need to shed light.
