OK, now, the current problem with syscall/exec_plan9.go is that it is a little too eager to close FDs. It's doing the close by hand because it's not possible on Plan 9 to take an fd and set to to close-on-exec -- that's only done on open on Plan 9 (on unix the code does an fcntl). But if an FD is used twice for a child -- as it is with combined stdout/stderr -- then the close closes the fd before it can be dup'ed a second time. Bad. I did the lazy thing and commented out the erroneous close for now. The easy fix is to track the fds to be closed in a map and then close them all later. That's next. Another possibility is to allow '#d/*ctl' to be writeable and implement a closeonexec control message for fds. But maybe that's just too much. It is certainly easy to do, but is that kind of feature something we want to add? ron
