The lowest delay pool is the one used, if any pool is zero the request is
delayed, you're right there (that's what delayBytesWanted() does, finds
the number of bytes to read).

But if you look where it actually decrements the bytes it takes them off all
relevant pools, hence all pools are consulted.

Oh and if you look where you were reading:
    case 3:
        if (Config.Delay.class3.aggregate.restore_bps != -1)
<---------
            nbytes = XMIN(nbytes, delay_data.class3_aggregate);
        if (Config.Delay.class3.individual.restore_bps != -1)
<----------
            nbytes = XMIN(nbytes, delay_data.class3_individual[position]);
        if (Config.Delay.class3.network.restore_bps != -1)
<----------
            nbytes = XMIN(nbytes, delay_data.class3_network[position >> 8]);

nbytes starts as the max number of bytes wanted and then is calculated as the
minimum of the current number wanted and the bytes remaining in each pool.
Hence it's the lowest delay pool, not the last one.
