Game hangs up at shutdown

[MCMic]

When quitting, the process hangs up. Here is the backtrace:

==40789== Process terminating with default action of signal 2 (SIGINT)

I see that there is this in the code for the pandora version, which I think is a dirty workaround for this problem:

#ifdef PANDORA
	// Hacky close on the Pandora :(
	raise(SIGKILL);
#endif
