   TCP connect, a proxy's reply, a handshake) has `connectTimeoutMs` to itself, so

+* `TlsSocket::connect` bounds the handshake with the `timeoutMs` it already
+  took for the TCP connect, so a caller of it directly sees the change too.
 * `TlsSocket::connect_over` takes a trailing `handshakeTimeoutMs`, `-1` (the

   the new parameter in its type. `Socket` gains `set_deadline`, `deadline_hit`
