Which is what everybody basically does. And when it works during the
decidedly non-rigorous testing, they move on to the next problem...
with code that doesn't perform well in the corner cases. Such as when
a host has just been renumbered or one of the host's addresses is
unreachable.

And because most everybody has made more or less the same errors, the
DNS TTL fails to cause their applications to work as intended and
loses its utility as a tool to facilitate renumbering.

::shudder::  I don't *want* to do anything in python. The occasional
reality of a situation dictates that I do some work in python, but I
most definitely don't *want* to.
