> BDB HA VirtualHostNode currently relies on the detach event from the JE to tell it that
it is no longer master.  HA acceptance testing has shown that sometimes this event might not
be generated by JE for sometime after we first learn we are restarting.   Whilst this does
not introduce a functional defect, it does mean the have more failed transactions and the
client fails a larger number of times.  It makes the logs harder to read.
> It might make Qpid more supportable if we send our own event to BDB HA VirtualHostNode
when we first learn we are restarting.  We can then have the BDB VirtualHostNode close the
VirtualHost early - preventing new connections and closing existing ones.
