- Avoid adding slow or blocking code in the GUI thread. In particular do not
add new `interface::Node` and `interface::Wallet` method calls, even if they
may be fast now, in case they are changed to lock or communicate across
processes in the future.
Prefer to offload work from the GUI thread to worker threads (see
`RPCExecutor` in console code as an example) or take other steps (see
https://doc.qt.io/archives/qq/qq27-responsive-guis.html) to keep the GUI
responsive.
- *Rationale*: Blocking the GUI thread can increase latency, and lead to
hangs and deadlocks.
