You're absolutely correct and you raise a very good point, Nic.

Clients (e.g. browsers) can (i.e. may) -- and frequently do -- open more than
one persistent connection to a given server in order to service a single end
user "request", and this could well be what Marc was observing happening.

Good catch. :)
