Ok (talked this through with jeff). The id_inner test isn't needed.
The case of GDB doing a nexti and ending up in a signal handler should
have been handled earlier (in time). At the point where the signal
first arrives - GDB should have set a breakpoint at the signal return
address and then continued the inferior with the signal.

Time to turn infrun.c into a state machine :-/
