Chris,

I've just written a little test program for fcntl(..., FD_CLOEXEC)
and it doesn't seem to be having any effect at all, i.e. the
exec'd program can happily read from a file descriptor it's parent
open'd and marked as close-on-exec.  So something's awry
somewhere.

I've attached the test program (in case I've made a hash of it):
call it as ./clexec_exec -1 and it should print out a chunk of
/etc/passwd (from the exec'd copy).
