Very big +1 to this. It is reasonable to think that detach is too short / not descriptive enough, but prepending spawn to it creates more semantic confusion than it solves. I have an alternative proposal over here, because we've found that we really need an alternative to detach. It both adds an API that subsumes the majority of uses of detach, and gives detach a more appropriately-descriptive name. Since it's an additional proposal, I've gone off and started a separate pitch thread rather than put more alternatives here.
