Brilliant; I had read the director page in the wiki but didn't see it there & a \
search of the wiki text doesn't show up the option - perhaps you could add it or is \
there another place to see a list of director options?

Already done, and enabled by default:

# How long to redirect users to a specific server after it no longer has
# any connections.
#director_user_expire = 15 min

I added this mainly to make sure that all attribute caches have timed out.
