Function waiting_elsewhere 

pub fn waiting_elsewhere(
    root: &Path,
    dir: &Path,
    feature: &str,
    task: &str,
) -> Result<Elsewhere, String>

Elsewhere for a run of task, read through the journal’s writer: one a killed run left unclosed is repaired, not taken for one where nothing waits.

Errors

The waiting calls cannot be read — the run cannot tell whether another attempt holds the worktree, so it does not start.
