This situation was so pervasive and compromising that we decided to
include handling for it in our production code.  The consequences of
users injecting requests from the stale windows that arise from the
assorted manifestations of "multiple browser windows" were too
problematic for our support side and and we felt that it left the users
doubting our software's hardiness and useability. 
A self-inflicted requirement to some degree, mainly to avoid a
perception of and criticism as "weak" software - irrespective of having
warned users not to open multiple windows on the same data object, and
making all claims that it's "not our software, it's http's issue". 
Consequently we've ended up with a web app that probably behaves a
little less like http://www.* and a little more like C:\Program Files\*
(which is what the generic manager thinks in terms of ... "MS Office
does it so why can't our website?")
There's probably less pain involved if you set out to manage that case
from the outset, rather than blending it in late.  Perhaps it would make
a nice plugin taglib for contribution to OS?
