Initiator.handleConnection dials with a context that is cancelled when the initiator stops,
but then calls tlsConn.Handshake(), which ignores it. If the peer accepts the TCP
connection but never completes the handshake, Initiator.Stop() blocks until the OS drops
the connection: minutes on a blackholed network, or indefinitely if the peer keeps the TCP
connection alive.
Using HandshakeContext(ctx) makes Stop cancel a pending handshake, just as it already
cancels the dial.
