I don't think that will be correct - it might be mostly correct, but "Juliet
gc pauses" are just an extra long version of what happens all the time. ZK
is asynchronous, so we will never find out immediately if we've been killed.
There can always be an arbitrarily long pause in between looking at ZK state
and taking an action.
