Comment (by strk):

 Removing this line from "handleInterrupt" fixes the problem for me:
 {{{
 printf("Interrupt requested\n"); fflush(stdout);
 }}}

 It turns out it was never a good idea to printf from the interrupt
 handler, exactly for the risk of being invoked again (and triggering a
 deadlock).

 See http://stackoverflow.com/questions/8738951/printk-inside-an-interrupt-
 handler-is-it-really-that-bad

 I'm going to push a fix
