list of handlers, callable by irqctl system call . workaround for hanging keyboard bug after shutdown.. if key is pressed during or after shutdown procedure, keyboard stops working. It looks like irq 1 gets stuck high if no keyboard reading is done (e.g. because the irq is masked or tty driver has exited). Workaround is to leave irqs enabled until the last second, and call shutdown() immediately after the last driver has stopped (tty task). This way the chance of an unserviced interrupt occuring is negligible.
