Comment 6 for bug 277082

GenerateConsoleCtrolEvent *might* be tricky to use in this case - IIUC, in practice it only works for processes that share the same console. In the case of tbzr, qbzr will not even have a console to share! I spent some time with the Zope project trying to use this function so a service could interrupt a child process of its own, but failed - we ended up implementing a win32 specific way to interrupt the child process.
