WHAT Attempting a failing RPC connection throws OSError: [WinError 10038] An operation was attempted on something that is not a socket

EXPECTED It should throw RPCError: can't connect to server (from this line

WHY See protocols.rpc._connect: in case there is an Exception, sock.setblocking(1) is called after sock.close()

Indeed that looks like a problem. Can you make a PR ?
