seconds without producing output on stdout or stderr (NIX-65). This timeout can be specified using the `--max-silent-time' option or the `build-max-silent-time' configuration setting. The default is infinity (0). * Fix a tricky race condition: if we kill the build user before the child has done its setuid() to the build user uid, then it won't be killed, and we'll potentially lock up in pid.wait(). So also send a conventional kill to the child.
