Switch the mirror commit_signal to an mbox

Browse Source 
At the moment, a first-pass failed migration will retry. This is wrong,
it should abort.  However, to make that happen the mirror supervisor
needs to know the commit state of the mirror thread.  With a self_pipe
mirror commit signal that information wasn't there.
