Unless the OS gives some way to optimize the process (whether inferring from procfs, or making use of spawn_closefrom), there really isn't anything we can do. O_CLOEXEC is one option, but that's basically the same as the close loop in terms of syscalls- specifically post fork looping over the range and setting it. Beyond that, it's linux specific, so only would be used if the root python was invoked from lacked procfs. I'm willing to extend my original patch to handle alternate OS hints as needed; in the same way, the nlinks trick I can implement although I'd be more inclined to just limit my original closerange patch to OSs that have a sane opendir and procfs. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue8052> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
