Maybe it's just the phrasing of the commit message but won't the new
socket that needs to be created immediately fail? I think this is
really just checking that you don't try to instantiate two different
sets of extensions on the same UDP port - it's not like this is going
to somehow create a new socket and they will be able to coexist.
