Since r87651, subprocess can raise a RuntimeWarning if pipe2() fails. I'm not sure there's any point in that, since it's very low-level and it's nothing the user can do about anyway. Ironically, there is no warning if pipe2() is not available at all.

This can be seen on the sparc Debian buildbot by the way: /home/pybot/buildarea-sid/3.x.klose-debian-sparc/build/Lib/subprocess.py:1085: RuntimeWarning: pipe2 set errno ENOSYS; falling back to non-atomic pipe+fcntl. c2pread, c2pwrite = _create_pipe() /home/pybot/buildarea-sid/3.x.klose-debian-sparc/build/Lib/subprocess.py:1144: RuntimeWarning: pipe2 set errno ENOSYS; falling back to non-atomic pipe+fcntl. errpipe_read, errpipe_write = _create_pipe() [etc.] http://www.python.org/dev/buildbot/all/builders/sparc%20Debian%203.x/builds/1/steps/test/logs/stdio
