arana crawls GitHub webpages for delicious data
Why not...?!
A spider.
A list of the tasks that need to be performed next. The work-queue is stored as a Sorted Set where the timestamp (when the task was added to the work-queue) is the "score" and the value is the url that needs to be crawled.

Question: should we add all links on a page to the work queue immediately
or only add links to the queue as we find them?
A: I think we need to add all related links to the queue immediately
to ensure that we get content-complete as quickly as possible.
