Well... if you're queueing biggest-packet-first, yes, the ssh can get starved
indefinitely if there's enough web browsers downloading pages or P2P traffic.

If you're queueing smallest-first and there's enough even-smaller packets to
starve an ssh session, you probably have bigger problems...

Yes, it *could* make connecting to shoot that port that's spewing ICMP at
line rates a bit challenging, but you knew that when you chose the queueing
algorithm, right?
