Yep ... but it is a strategy I recall from my C++/COM days which I still
shudder at ;) I remember quite a few cases where I had to debug each others
code because components where forced to be shutdown and couldn't gracefully
go down. Especially when there is circular dependencies that creep in without
you noticing ;)

True it is easier in shortterm and much less complex.
