Chirantan Ekbote a00991cd84 Replace dup with fcntl(F_DUPFD_CLOEXEC)
Fds created via dup don't share file descriptor flags with the original
fd, which means that they don't have the FD_CLOEXEC flag set.  Use
fcntl(F_DUPFD_CLOEXEC) so that this flag gets set for the duplicated fds
as well.

BUG=none
TEST=unit tests
