After looking more closely at patch 2, this seems to suggest we're not
understanding the OFFLINE/ONLINE events well enough to use for this
purpose.  I think this patch won't be needed once we address the
concerns in patch 2 - and more generally if we discover it is needed
this should just be rolled into patch 2 rather than kept separate.
