I see. The number of cmd.exe's running was not *that* big though: about 
5-10 I would say. And their PID's kept changing.

I took a look with Process Explorer from sysinternals, which shows the 
processes as a tree instead of a simple list. Apparently each fake_nmap 
is a child of a cmd.exe, meaning that os.popen indead uses the shell to 
run processes. I wouldn't be surprise if cmd.exe would be the culprit here.
