Try this:

print "Hit a key!"
cekaj()
print "Nap time!"
time.sleep(15)
print "Hit another key!"
cekaj()

with the two different implementations, and see what happens if you hit a key 
when the 'Nap Time!' prompt appears.

Cheers,
Nick.

P.S. You probably actually want an implementation that looks like:

def cekaj(prompt="Press a key to continue"):
     while msvcrt.kbhit():
         msvcrt.getch()
     if prompt is not None:
         print prompt
     msvcrt.getch()

And the sample program would look like:
cekaj("Hit a key!")
print "Nap time!"
time.sleep(15)
cekaj("Hit another key!")
