# We are hacking net/http to change semantics of streaming handling
# from "block" semantics to regular "return" semantics.
# We need it to construct a streamable rack triplet:
#
# [status, headers, streamable_body]
#
# See http://github.com/zerowidth/rack-streaming-proxy
# for alternative that uses additional process.
#
# BTW I don't like monkey patching either
# but this is not real monkey patching.
# I just added some methods and named them very uniquely
# to avoid eventual conflicts. You're safe. Trust me.
#
# Also, in Ruby 1.9.2 you could use Fibers to avoid hacking net/http.
