cons_read is in a Interrupt Gate like all our interrupts. Whenever it's called, interrupts are disabled, and are re-enabled later on IRET.

Problem it is has to wait for the keyboard, right now we do this like:

        while (keyboard_buffer[index_read] == 0) {
            // wait for a character
            sti();
            hlt();
            cli();
        }

which re enables interrupts and allows keyboard interrupts to happen again, but there's probably another way.
