Subject: [SDL] signal handling bug
I encountered the following bug:
SDL doesn't reset signal handlers for SIGTERM and SIGINT, after calling SDL_Quit these remain hooked to the handler in SDL_quit.c, being translated into SDL_QUIT events.
Consequently an application that issues a SDL_Quit and remains running will ignore any SIGTERM or SIGINT., and specifically CTRL-C presses.
