Berenguer Blasi commented on CASSANDRA-16644:
---------------------------------------------

[~e.dimitrova] I have been testing this with diff timeouts and they are either 
too short or too long so the failure can't be repro'd like that unfortunately. 
So I looked at your patch and I think it is the right thing to do indeed to get 
some more info. I can't explain why you didn't repro bc you have the same exact 
code I would have produced :shrug: Would you mind running it again? maybe this 
time we'll be lucky. Otherwise we'll ask Andres which is in good terms with the 
bug repro Gods and see if he can with your patch.
