rP84049ed4793c: (stable) Prevent external connections from being mutated on held locks
rP466013f11a6d: Prevent external connections from being mutated on held locks
Summary

Ref T13627. This makes the API harder to misuse: setting an external connection on a held lock isn't a meaningful operation. Prevent it.

Added a failing test, made it pass.
