Code looks fine. Would probably want to do a test with a bunch of scheduled queues to see what performance improvement it makes to make sure we understand how this helps.

This reduces Redis ops with N idle workers from from
6 + 4 * (N-1)to7 + 1 * (N-1)per second.For example, if 100 workers are idle, Redis queries would be reduced from 402 down to 106 per second.
