Looks like notify actually can throw an exception... the way I 
usually do signal handlers is just set a global variable:

__global bool interrupted = false;
void sigint_handler() { interrupted = true; }

then in the main loop check that periodically... idk if that'd 
work well withthe condition variable though, I have never 
actually used that...
