Thanks, Kent, but I'm afraid I don't know what a blocking call is.

Yes, I only want to run on Windows.

================
import msvcrt
c = 0
while True:
     c += 1
     (What goes here?) #  Not 'if msvcrt.getch() == "k":', it seems.
         break
print c
================

What I want to do is start the loop spinning, then hit "k" at some 
point, and see what c is.
