What's the problem? Describe what went wrong in few words.
Dolphin does not terminate on SIGTERM or SIGINT.

What did you expect to happen instead?
Dolphin should terminate.

What steps will reproduce the problem?

1. Start Dolphin.
2. Run "killall dolphin-emu" or press Ctrl+C.
3. Nothing happens.

Which versions of Dolphin did you test on?
master (4.0-6571, 97382ec90a8c960d12836aa5b979e70da40bb9f5)

What are your PC specifications?
Linux with SDL 2.0.3

Is there any other relevant information?
This issue is caused by SDL. SDL_INIT_JOYSTICK implies SDL_INIT_EVENTS, which installs signal handlers for SIGTERM and SIGINT and translates them into SDL_QUIT events. http://hg.libsdl.org/SDL/rev/0979c3e31211 (to be released in SDL 2.0.4) provides a way to prevent this:

SDL_SetHint(SDL_HINT_NO_SIGNAL_HANDLERS, "1");
