1.7.1: terminal not passing Ctrl-C to sub-sub cygwin processes


From within cygwin python, if I call os.system running a cygwin sub-process, and I hit Ctrl-C while that cygwin sub-process is running, the Ctrl-C does nothing (absolutely nothing -- nothing is printed, nothing terminates, no sound is made -- it's as if I didn't press the key at all).

I've attached a simple script which easily reproduces the situation. When I run the script as "./ctrlc.py 0", Ctrl-C kill the process, but when I run it with an argument of 1 or more, hitting Ctrl-C has no effect.

I have not testing this with anything other than python, but I have a feeling that it's not python related.
