Well there you go. Once people are satisfied with the extent to which O_CLOFORK and FD_CLOFORK are present in operating systems, the coproc keyword could simply apply that fd flag to the fds it creates. A builtin 'fdflags' or similar could then turn it off for those fds or on for any arbitrary fd. I'd be willing to wait for that. It seems like a really elegant solution. Zack
