This looks good to me, though it definitely doesn't fix #831 |

Agreed, but it does fix something in that it makes io.js a little more robust and secure. BTW, CI: https://jenkins-iojs.nodesource.com/view/iojs/job/iojs+any-pr+multi/178/ |

Check that stdin, stdout and stderr map to open file descriptors and remap them to /dev/null if that isn't the case.

When checking for the validity of the stdio file descriptors (nodejs#875), ones which don't exist are intended to be remapped to /dev/null (and, if that doesn't work, we abort). This however doesn't work on all platforms and in all cases (e.g. /dev/null could already have been opened by the acting process and not actually be mapped to the expected file descriptor); instead, use the `dup2` syscall as a more robust solution (conforms to POSIX.1).
