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 .....
