How do you know this? Do you check the session variables to see whether
they persist beyond timeout? I ask, in view of the following.

if someone is idle for 10 min and Coldfusion times their session out,
they might not exist any longer for you to kick them out. You should therefore
not wait for the the user to be sent back to the admin login page, as a sign
that their session has timed out. You could wait forever, while CF had indeed
timed them out.
