Can we find a better argument name than ``_bind_stdout``? Maybe ``path`` or
``stdout_path``?
> Diagnostic log rolling races
> ----------------------------
>
> Key: TS-4072
> URL: https://issues.apache.org/jira/browse/TS-4072
> Project: Traffic Server
> Issue Type: Bug
> Components: Logging
> Reporter: James Peach
> Assignee: Daniel Xu
> Fix For: 6.2.0
>
>
> When diagnostic logs are rolled, {{Diags::diags_log}} is deleted and replaced
> with a new log object. Since the global {{diags}} points to a a single
> {{Diags}} object there is nothing to prevent a different thread logging
> through this object at the time it is deleted.
