...pen some resources. Would it be possible to add an option to close file descriptors for child processes? It would be nice if that were the default, but I suspect that making that change would break a lot of existing code. To take an example from the Python world, subprocess.Popen() has an option, close_fds, which closes all file descriptors except 0, 1, and 2. https://docs.python.org/2/library/subprocess.html#popen-constructor -Winston [[alternative HTML version deleted]]

I've been trying to cut down the size of openssh so I can run it on my Nokia 770. One thing which helps a fair amount (and will help even more when I get '-ffunction-sections -fdata-sections --gc-sections' working) is to have the option of compiling out privilege separation... Is it worth me tidying this up and trying to make it apply properly to the OpenBSD version? Does the openbsd
