> In our production cluster, we are seeing a large number of dropped mutations. At a minimum,
we should print the time the thread took to get scheduled thereby dropping the mutation (We
should also print the Message / Mutation so it helps in figuring out which column family was
affected). This will help find the right tuning parameter for write_timeout_in_ms. 
> The change is small and is in StorageProxy.java and MessagingTask.java. I will submit
a patch shortly.
