Description

[Description of the issue]

When there are multiple links available, the queues are filling in a first in, first out manner instead of a round robin.

With 5 links , i have 4 videos to process. Each link has 2 workers, so 2 preloads. I now have 2 hosts with Pending tasks and 1 processing task, instead of 4 of 4 hosts with 1 task and 1 idle host.
