I've been mulling over ways to do non-blocking keyboard reads without
polling the keyboard; is there any way that I can be signalled when the
console device has input available short of creating a new task to block 
for input and then signal its parent process?

That is, if I am waiting for the timer to wake me up, but I need to be notified 
of any keystrokes that may occur in the meantime, is there anything simple
(short of busy-waiting) that I can do?
