I'm waiting for Studio too :)
Then yes, we should have a look at the code together. I need somebody to
review it.

Yeah, i guess i am obscure on that, messed up with the terminology :) I was
trying to say:

Every individual component type will have its own automatically generated
schema elements and entries on ApacheDS. HouseKeeping will make sure we
keep ApacheDS clean of those schema elements and entries of component's
which is not been seen for a while. While saying session, i was referring
server start-stop cycles. So what is my mind is, when server is started and
stopped 3 times wihout having some component's bundle in its Felix folder,
then all previous schema elements and entries belonging to it will be
removed. But we can discuss it later as i said...
