continued refactor (safe state) connector internals are (mostly) read-only until the moment the round succeed, whereafter the changes to ports/connectors are committed by being folded in

- After connecting, ports can exchange messages
- Message exchange is conducted in two phases:
1. preparing with `connector_put`, `connector_get`, and
2. completing with `connector_sync`.
This paradigm is similar to that for sockets in non-blocking mode.
- The connector stores messages received during sync. they can be inspected using `connector_gotten_bytes`.
- Ports created using `connector_add_port_pair` behave as a synchronous channel; messages sent in one end are received at the other.
