Many thanks for finding this (and fixing it!). I hope Jacques picks this up.

The code to handle the bind(0.0.0.0) case is unfortunately based on some
linear searches (and might even be as bad as O(N^2)) so the idea was to cut
down on the searching and optimise for the common case of only allowing one
IP and localhost per context.
