error.Error.is_transient(self) -> bool
```

Report whether retrying the same call unchanged is safe and may succeed.

`true` means this error proves that the requested mutation did not run,
or came from an operation that only reads state. The condition may need
to clear first: capacity can become available, a client can resume, a
resource-limited spawn can be retried, or a server can answer again.

`false` does not mean that the handle is unusable. A subprocess timeout,
output-reader failure, child-wait failure, or lost supervisor can leave
the executor ready for another call, but tmux may already have carried
out the first one. Replaying a mutation could duplicate its effect. A
shut down executor and a closed or timed-out control connection are also
false because they require a new server or connection.
