Discussing on python-dev is fine. An acceptable solution would be to
omit setitimer/getitimer on FreeBSD if the FreeBSD version is "wrong",
either at configure time or at compile time. An even better solution
would be to test at configure time whether these functions work, and
refuse to expose them if they don't (not sure whether that's possible,
though, as I don't know when the choice of threading library is made).
