I see three ways to solve this:

One would be to have a private %deadhost in getsnmparg()
Another would be a global %deadhost in mrtg
A third way would be to pass a reference to a global %deadhost to

Neither of these three options seem very good, though I myself like the
first one the best, but closures are quite unreadable.

What do you think?
