> CASSANDRA-8099 merged the way single partition and range read messages where 
> handled and has switch to using the same verb ({{Verb.READ}}) for both, 
> effectively deprecating {{Verb.RANGE_SLICE}}. Unfortunately, we are relying 
> on having 2 different verbs for timeouts. More precisely, when adding a 
> callback in the expiring map of {{MessagingService}}, we use the timeout from 
> the {{Verb}}. As a consequence, it's currently set with the single partition 
> read timeout (5s) even for range queries (which have a 10s timeout).  And 
> when a callback expires, it is notified as a failure to the callback (which 
> is debatable imo but a separate issue), which means range queries will 
> generally send a ReadFailure (after 5s) instead of a ReadTimeout (since they 
> do wait 10s before sending those).
> That is the reason for at least the failure of {{nosetests 
> replace_address_test:TestReplaceAddress.replace_first_boot_test}} dtest (the 
> test has 3 nodes, kill one and expects a timeout at CL.THREE but get a 
> failure instead).
