Were there any other patches that needed testing? It changed a few times since I first looked at it and there were other approaches that had more patches but this single patch is what I have come up with most recently. One problem is that with any change that I can come up with the limit on request call backs (the ELOOP return that's seen) is removed and that means it's possible to get a tight call back loop with no exit condition. For a long time I was most concerned about this but now I'm thinking this is a sufficient improvement, at least for the most common use case and I think a couple of not so common cases, to go ahead with it anyway as a similar call back problem is possible when not using namespaces any way. The daemon does handle that sufficiently well now so .....
