I'm not questioning "why" vim set out_io and err_io, but what I had written just above what you quoted: « possibly it's "all readable fds are closed" that somehow is detected differently on GNU/Linux and GNU/Hurd. » Only out_io and err_io are supposed to be readable. Or did they mean from the point of view of the executed process. Again, it means check what exactly happens to end up with "all readable fds are closed" Samuel
