IIUC, if any of the notifiers will actually start to fail, say, during 
MIG_EVENT_PRECOPY_SETUP, you will call MIG_EVENT_PRECOPY_FAILED on all 
notifiers.

That will include notifiers that have never seen a 
MIG_EVENT_PRECOPY_SETUP call.

Is that what we expect notifiers to be able to deal with? Can we 
document that?
