There's the "any" trigger that might be appropriate for that, or a
"disconnect" trigger.

But I'm basically thinking the same as Steve - if you're never going to
wake up the host, there's not really much point in keeping the
connection, and if you only suspend briefly like e.g. on Android then
you probably *do* want to wake up the host for pretty much everything
that's going on (hence the "any" trigger).
