> already possible to implement pipe2.
For reference, the introduction of pipe2 in Linux was here:
http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.28.y.git;a=commit;h=ed8cae8ba01348bfd83333f4648dd807b04d7f08

Now the 'pipe' module can make use of 'pipe2':
2009-08-22 Bruno Haible <br...@clisp.org>
* lib/pipe.c (create_pipe): Use pipe2 instead of _pipe.
* modules/pipe (Depends-on): Add pipe2.
