[x] How many retries by default - has this timed-out after multiple attempts, or just one?
Retries is only for INSUFFICIENT_RESOURCES error, wont retry on 504
[ ] why not reporting failure back up chain from _fetch_query to CrawlManager
Decision in DAC.ArchiveItem._fetch_query not to report errors but work on existing. Need at least an option to request this, and pass this up to crawler.
STR
Watch for 504 Notice that no error reported at end of crawl, notice also that query isn't retried
