So -- how does system(1,"foo") work on Windows?

It just calls CreateProcess with the CREATE_NEW_PROCESS_GROUP flag bit set. See Win32::Process for the details.

It's a bit more complicated as it has to arrange for wait and waitpid to work.

    Do you know why CREATE_NEW_PROCESS_GROUP flag is used ? It is a problem because child processes no longer respond to Ctrl+C, while the main script does. Then the main script exits on keyboard interrupt, but child processes linger in the background where no onne can see them.
