The refresh-translatable-page.php script spawns a number of RenderTranslationPageJob that are considered high traffic jobs.
This causes RenderTranslationPageJob jobs that are generated as a result of user translations to be delayed causing translation page updates to take a very long time. See: T352846: Delay in creation or editing of translation pages
We can do something similar to what RefreshLinksJob does to avoid this situation from happening. See: https://codesearch.wmcloud.org/search/?q=refreshLinksDynamic&files=&excludeFiles=&repos=
