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.
The reference for a request verb is now the string which is used
everywhere else, instead of the symbol corresponding to it. This was an
artifact from the import from httprb, and there is no advantage in it,
since these strings are frozen in most use cases, and the
transformations from symbol to strings being performed everywhere are
prooof that keeping the atom isn't really bringing any benefit.
This type of lookup was guarded in the first DNS query lookup, however
after recursive CNAME queries, this could trigger a case where an AAAA
query would fetch cached A records, which would be filtered out but
still delivered.

to wait for.
Timeout calculation may trigger errors which lead to connection
unregistering, such as tital timeout errors. In such a case, we can end
up in a state where #select gets called with no timeout and no
selectable connections.
