Yes, but the problem is what to do with the /* Do something useful here */.
Because signal_handler can be called from any position in the code (for
example, it may be in the middle of a malloc), it's unsafe to do much
more inside signal_handler than to set a variable as a flag (I'm not
even sure if puts would be allowed inside signal_handler). And then the
question is how to let gtk_main know that the flag variable has changed.
