I have not analyzed the cost of the network init code.
I assumed there is some significant cost, otherwise
those other init calls could just do the network init
and this separate function is useless and the printout
spam pointless.
Either way around, I can't figure out any explanation
that ends with anything other than this API and message
being idiotic.
