You can use nonblocking I/O, e.g., setup getch() to read with a short 
blocking time, and wrap getch() in a function that periodically updates
the clock.  Several of the test programs in ncurses use nonblocking I/O,
e.g., nodelay() with napms() or wtimeout() to poll for keyboard input
while updating the display.
