For buggy distributions of gethostbyname(), we supply our own version.
We don't just barrel ahead and tell them to fix it, if we can avoid it.
I don't see us bundling a fixed python, however. I realize it is only
Red Hat, but that is a large userbase.
I still do not know why we can't do some kind of runtime test in python
and disable this feature for 2.4 builds that have debugging enabled.
Can we do a dynamic function load test from plpython? There must be
some function that is only visible in debug builds.
