One more reason to at least not use the patch as you have it right now.
 If a file descriptor was opened with O_CLOEXEC but subsequently the bit
has been reset using fcntl() the f_flags value would still have the
O_CLOEXEC bit set.

If you don't like the separate cloexec line, at least reset the
O_CLOEXEC bit in the f_flags output if the FD_ISSET() test returns zero.
