any reason why the '0.0.0.0' is necessary? (the socket got created with
undef before after all) - Given that I find the inner workings of perl
IO::Socket::IP (which gets passed the arguments in create_reusable_socket
eventually) a bit surprising in certain situations I think leaving it as
it was might have its merit

did you test it in a few different scenarios? - e.g.:
* ipv6 only host
* dual-stacked host
* host with multiple interfaces and IPs
