> Scenario: A larger node (in terms of data it holds) goes down. You realize 
> that it will take slightly more than `max_hint_window_in_ms` to fix it. You 
> have a the disk space to store some additional hints.
> Proposal: Support changing `max_hint_window_in_ms` at runtime. The change 
> doesn't have to be persisted somewhere. I'm thinking similar to changing the 
> `compactionthroughput` etc. using `nodetool`.
> Workaround: Change the value in the configuration file and do a rolling 
> restart of all the nodes.
