    According to POSIX and my manual page on Linux, sysconf() return type is long (and not int).
    http://pubs.opengroup.org/onlinepubs/009695399/functions/sysconf.html

    It may not mater in practice because most sysconf() results are smaller than 1000, and I failed to find a value bigger than 2 millions.

    That looks reasonable to me.

    The bug does also exist in Python 2.7, 3.2 and 3.3, but I prefer to not fix it in these versions because I'm not 100% sure that the return type is long on all platforms and because nobody noticed the issue since years. So if I broke something, I prefer to only break the development branch ;-)

    I applied the fix to Python 3.4 and so I'm closing the issue.
