The delay pools in Squid is not quite that smart / dynamic. Delay Pools
is a bandwidth cap with selected requests scheduled within each defined cap.

You can do both (1) and (2) with a single class 2 pool shared by the
entire LAN (1310720 Bps aggregate, 655360 Bbps individual), and a
delay_pools_access denying wikipedia domains being pooled by it.

But having (3) where transaction X changes pooling mid-way depending on
some unrelated transaction is simply not possible.
