I don't think any requests should be sent in this case: the current 
coordinator should add the LEAVE(s) into its queue, as if it indeed did 
receive 2 LEAVE requests. This may or may not lead to rebalance, 
depending on the rebalance policy (e.g. JOINS are queued, but LEAVES and 
MERGES trigger a rebalance immediately).
