Well, yes.  There aren't really any good solutions with our event driven
model - we never "finish" booting, we just get to a point where nothing
has been happening for a while.  I have been thinking that we need to
just admit that properly and do something timer based - have a timer
that gets reset every time we instantiate something, then do all our
"end of boot" actions when nothing happened for a while.  It's not
elegant but I don't think elegant is a realistic goal here.
