> When the AntiEntropService sends the snapshot repair request, it sets up a callback in
an ExpiringMap. If the time it takes for the snapshot exceeds the RPC timeout, the callback
will expire from the map and the snapshot responses will be dropped. The repair then gets
stuck forever blocking at the snapshotLatch.  It's not even possible to kill the repair with
forceTerminateAllRepairSessions()
> This is likely fixed in 2.0 since that part of the code is completely rewritten.
