Subject: [PATCH] Use the BasicSocket#do_not_reverse_lookup flag in Webrick

Hi

With this patch you can make use of the new per-socket do_not_reverse_lookup flag in Webrick.
I wonder if it would make sense to even set :DoNotReverseLookup to true as the standard configuration because reverse lookup just slows down the server in normal operation.
