Nice stuff.
Some q:
- When a node CM that has c1 and c2 caches running on it goes down, you'll
end
up having REQUEST_LEAVE(c1) and REQUEST_LEAVE(c2) at the same time. Is
this handled in serial or in parallel?
In parallel, although that shouldn't matter because the rebalance is
triggerred asynchronously.
- The view updates can be disabled dynamically
(DISABLE_VIEW_UPDATES).
Shouldn't we also be able to re-enabled them manually
after that?

Shouldn't this be:
- acquire exclusive lock
- updates the pending view
- release lock
?
Right, what I meant to say is that it doesn't hold the lock for the entire
duration of the rebalance task.
