Hi Dave:

Right -- they are variables, not independent activities.

However, you need a better example -- queueing is not a major source of
delay in most of the Internet these days.  And the one place it
seems to be present, in wireless networks -- the issue is often
channel access delays (which is probably a better illustration of your
point anyway).
