Research direction

The issue names TcpStream::peer_addr but no source file or test. Reproduce the listed connection failure on Windows and compare its response timing with other platforms, then trace the platform-specific implementation. Done means the Windows failure response no longer exhibits the reported delay, with behavior covered by an appropriate regression test.
