Multiple fixes to prevent file descriptor leaks: - libxev eventfd now uses CLOEXEC - linux: cgroup clone now uses CLOEXEC for the cgroup fd - termio pipe uses pipe2 with CLOEXEC - pty master always sets CLOEXEC because the child doesn't need it - termio exec now closes pty slave fd after fork There still appear to be some fd leaks happening. They seem related to GTK, they aren't things we're accessig directly. I still want to investigate them but this at least cleans up the major sources of fd leakage.
