There is no such notification. The expectation is that setup and 
teardown actions are synchronised/communicated 'out of band' (usually 
via xenstore).
Anyway, a notification alone would not be much use -- how will the 
receiver know that this particular notification means the remote end 
has gone away? Adding extra teardown bits and pieces to the 
event-channel interface seems unnecessary when we provide xenstore for 
these control-plane setup/teardown activities.
