No bug, that is how delay pools are designed. Squid always fetches as 
fast as it can so as to finish with the more expensive network resource 
(port numbers) faster and free them up for other traffic sooner.

Use QoS controls in your operating system for that. Delay pools in Squid 
were designed long before QoS existed. Modern TOS/QoS capabilities are 
much better than Squid can do.
