I have seen setups where people actually have a cluster for slow actions that use a very low (probably 1) queue here, and then a cluster for "normal" actions (< 100ms or whatever), that use a longer queue. Again, this really depends on proxy, but the idea is to balance wait time vs. accept delay, as I'm sure you've inferred.
