Nicely documented. Aside from the use of clone() instead of connect() this is pretty much the other option I mentioned, using InactiveDestroy to disable disconnect() on parent handles in the kid. My experience with doing it this way was not great - inevitably something in a child process would stumble on a parent handle and either try to use it or disconnect it. Either will cause unpredictable mayhem, which is the very worst kind.
