Comment (by starlight):

 KIST scheduler is effective at minimizing data queued on egress socket
 buffers, but ingress socket memory is determined by the TCP/IP stack and
 remote peer behavior.  Perhaps then 150% of MaxMemInQueues provides a
 better margin?  A Shadow test simulating all-out botnet attack scenarios
 would help greatly determining extreme worst-case memory consumption.
