It adds flag parameters in all the places where none is present to
control aspects of the returned file descriptor(s).  So far atomic
close-on-exec and setting non-blocking mode are implemented.  More can
follow if wanted.  Similar to the O_CLOEXEC and F_DUPFD_CLOEXEC
extensions which I wrote several moons ago.  Just two weeks ago I pointed at

   http://bugzilla.redhat.com/show_bug.cgi?id=443321

as a case which we cannot really fix without these kind of extensions.
