add CLOEXECs
Ensure that open file descriptors do not leak across an execve()
boundary by setting the O_CLOEXEC flag on them. Leaking file descriptors
to exec()d processes may prevent file descriptors from being properly
freed, introduce security bugs if the child process is untrusted, and
causes problems for systems like SELinux which perform strict checking
of passed file descriptors.
