this made several plugins unusable with the proxy plugin, because a lot
of them are dependent on Connection#send being called and overwritten.
This was done so to avoid piping requests when intermediate
connect-level parsers are in place. So in the way, when the conn is
initial, original send is closed; when not, which should almost never
happen, a second list is created, which is then piped when the
connection is established, back to original send.
