As long as you don't have frames or some other pathological case where
multiple clients try to read and write from the same session data
object, no conflicts will happen during "normal" processing.  But since
session data object expiration happens in-band (it happens every so
often during normal request processing), you may see clumps of conflict
errors every few minutes as it purges old session data objects and
readjusts its index structures.

I think the plumbing is in there but there was some controversy over the
UI, so it's not in there.. ;-)
