I also submitted this pacth.

(Sorry but in Japanese.)

However, I think that applying is difficult for it since this method
(BasicSocket.do_not_reverse_lookup) influences the whole webrick server.
http://www.rubycentral.com/book/lib_network.html#BasicSocket.do_not_reverse_lookup

I think that it is necessary whether IPSocket#peeraddr can receive
"do not reverse lookup flag" or not.

for example,

  IPSocket#peeraddr()
    reverse lookup owing to BasicSocket.do_not_reverse_lookup.

  IPSocket#peeraddr(false)
    reverse lookup always.

  IPSocket#peeraddr(true)
    DO NOT reverse lookup always.


Or it should stop using IPSocket#peeraddr and ruby's Resolv library
should be used for reverse lookup.
