The namespace join facility looks interesting. Do you have a patch somewhere for it?

I'm not sure if the lack of isolation is any different than what can be done with a child process that shares the namespace.

I think that it can be depending on how much time you have spent building up a namespace for a process. Perhaps I have spent hours working on something slowly customizing the namespace mounting and binding things. If I end up running a long running command that blocks and I want to work in parallel with it then I must remember everything that I have done and repeat in a new window. It seems like something the computer should do for me or at least help me to do it.
