[SDL] failure at SDL_AddEvent()

[Daniel Goertzen]

Should work as long as you never ever modify session->event from the main
thread while timers are on.  Maybe try something like to make sure you
aren't tripping yourself up on the threading:

static Uint32 sdl_timer_callback(ep_session *session) {
SDL_Event event;
<fill in event with CONSTANT values>
 SDL_PushEvent(&event);
 return (55);
 }

Cheers,
Dan.
